TM74HC595

CMOS Shift Register TM74HC595 Characterization TM74HC595 is an open-drain output CMOS shift register which is designed with controllable tri-state output terminals and, when in serial output configuration, can control cascade chip of next stage. This product is excellent in performance and reliable in quality. Features     High-speed shift clock frequency Fmax> 25MHz Standard SPI CMOS serial output, capable of cascading multiple devices Low power consumption: Icc = 4μA (MAX) when TA = 25 ℃ Block diagram of internal structure 1 www.titanmec.com ©Titan Micro Electronics V1.1 CMOS Shift Register TM74HC595 Pin arrangement QB QC QD QE QF QG QH GND 1 16 2 15 3 14 4 13 TOP VIEW 5 12 6 11 7 10 8 9 VCC QA SI CE RCK SCK SCLR SQH TM74HC595 Pin Function Pin Name QA—QH Pin No. Function Description 15、1、2、3、4、5、 6、7 Tri-state output pin GND 8 Negative power SQH 9 Serial data output pin SCLR SCK 10 11 Clear pin of shift register Input pin of data shift clock RCK 12 Input pin of Latch clock OE SI 13 14 Output enable pin Input pin of serial data VCC 16 Positive power Input and output equivalent circuit VCC VCC INPUT OUTPUT GND GND Output pins 输出管脚 Input pins 输入管脚 ESD protection An integrated circuit is a static sensitive device. Since a considerable amount of static electricity is likely to be generated in a dry season or a dry environment and electrostatic discharge will damage integrated circuits, it is the advise of Titan that preventive measures should be taken for all appropriate ICs are. Improper operation and welding may cause ESD damage or performance degradation, and put the chip out of service. 2 www.titanmec.com ©Titan Micro Electronics V1.1 CMOS Shift Register TM74HC595 Recommended Operating Conditions Tested at -45 ℃ ~ + 85 ℃ , unless otherwise stated Parameter Parameter Symbol Name DC VDD DC input voltage DC output voltage Operating temperature TM74HC595 Test Conditions VCC VIN VOUT TA VCC =5V Unit Minimum Maximum 2.0 0 0 5.5 5.5 VCC V V V -55 125 ℃ Electrical Characteristics Unless otherwise stated, tested at VDD = 3.0V ~ 5.5V and the operating temperature of -40 ℃ ~ + 85 ℃ Test Conditions Parameter Parameter VDD Name Symbol Input high level VIH Input low level VIL Output high level (SQH) VOH Output high level (QA- QH) VOH Output low level (SQH) VOL Output low level (QA- QH) VOL Quiescent Current ICC 2.0 4.5 6.0 2.0 4.5 6.0 2.0 4.5 6.0 4.5 6.0 2.0 4.5 6.0 4.5 6.0 2.0 4.5 6.0 4.5 6.0 2.0 4.5 6.0 4.5 6.0 6.0 TM74HC595 25℃ Min 1.46 3.23 4.30 Typ Max 0.52 1.32 1.77 VI=VI IO=-20μA H or VIL IO=-4.0mA IO=-5.2mA VI=VI IO=-20μA H or VIL IO=-6.0mA IO=-7.8mA VI=VI IO=20μA 1.9 4.4 5.9 4.18 5.68 1.9 4.4 5.9 4.18 5.68 H or VIL IO=4.0mA IO=5.2mA VI=VI IO=20μA H or VIL Unit Value IO=6.0mA IO=7.8mA VI=VCC or GND 2.0 4.5 6.0 4.31 5.8 2.0 4.5 6.0 4.31 5.8 0.0 0.0 0.0 0.17 0.18 0.0 0.0 0.0 0.17 0.18 0.1 0.1 0.1 0.26 0.26 0.1 0.1 0.1 0.26 0.26 4 -40℃—85 ℃ Min Max 1.46 3.23 4.30 0.52 1.32 1.77 1.9 4.4 5.9 4.13 5.63 1.9 4.4 5.9 4.13 5.63 0.1 0.1 0.1 0.33 0.33 0.1 0.1 0.1 0.33 0.33 40 -55℃—125 ℃ Min Max 1.46 3.23 4.30 0.52 1.32 1.77 1.9 4.4 5.9 4.10 5.60 1.9 4.4 5.9 4.10 5.60 0.1 0.1 0.1 0.40 0.40 0.1 0.1 0.1 0.40 0.40 80 V V V V V V μA 3 www.titanmec.com ©Titan Micro Electronics V1.1 CMOS Shift Register TM74HC595 Switching characteristics Unless otherwise stated, tested at VDD = 3.0V ~ 5.5V and the operating temperature of -40 ℃ ~ + 85 ℃ Para mete Test Parameter Name r Conditi Sym ons bol TM74HC595 TA=25℃ TA=–40 ～ 85℃ TA=-55 ～ 125℃ Range Range Range Un it SI-to-SCK ON time tsu VDD=3.3 VDD=5.0 3.5 3.0 3.5 3.0 3.5 3.0 ns SCK-to-RCK ON time tsu(H) VDD=3.3 VDD=5.0 8.0 5.0 8.5 5.0 8.5 5.0 ns SCLR-to-RCK ON time tsu(L) VDD=3.3 VDD=5.0 9.0 5.0 9.0 5.0 9.0 5.0 ns SI-to-SCK OFF time th VDD=3.3 VDD=5.0 1.5 2.0 1.5 2.0 1.5 2.0 ns SCLR-to-RCK OFF time th(L) VDD=3.3 VDD=5.0 0 0 0 0 1.0 1.0 ns SCLR-to-SCK recovery time trec VDD=3.3 VDD=5.0 3.0 2.5 3.0 2.5 3.0 2.5 ns Pulse width of SCK or RCK tW VDD=3.3 VDD=5.0 5.0 5.0 5.0 5.0 5.0 5.0 ns SCLR pulse width tW(L) VDD=3.3 VDD=5.0 5.0 5.0 5.0 5.0 5.0 5.0 ns 4 www.titanmec.com ©Titan Micro Electronics V1.1 CMOS Shift Register TM74HC595 Timing Characteristics Function Description Input pin Output pin SI SCK SCLR RCK OE X X X X H QA-QH output high impedance X X X X L QA-QH output RMS X X L X X The shift register is cleared H X X L is stored into the shift register H X X H is stored into the shift register H X X Hold the shift register state X Output the status value latched in the shift register X Hold the output status of the shift register L H X Rising edge Rising edge Falling edge X X X X X X Rising edge Falling edge 5 www.titanmec.com ©Titan Micro Electronics V1.1 CMOS Shift Register TM74HC595 Schematic diagram of packaging (SOP16) 6 www.titanmec.com ©Titan Micro Electronics V1.1 CMOS Shift Register TM74HC595 Schematic diagram of packaging (DIP16) All specs and applications shown above are subject to change without prior notice. 7 www.titanmec.com ©Titan Micro Electronics V1.1
