The SN74ALVCH162344 is used in applications in which four separate memory locations must be addressed by a single address. The outputs, which are designed to sink up to 12 mA, include equivalent 26-Ω resistors to reduce overshoot and undershoot. To ensure the high-impedance state during power up or power down, the output-enable (OE) inputs should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended. 1 56 2 55 3 54 4 53 5 52 6 51 7 50 8 49 9 48 10 47 11 46 12 45 13 44 14 43 15 42 16 41 17 40 18 39 19 38 20 37 21 36 22 35 23 34 24 33 25 32 26 31 27 30 28 29 OE4 8B1 8B2 GND 8B3 8B4 VCC 8A 7B1 7B2 GND 7B3 7B4 7A 6A 6B1 6B2 GND 6B3 6B4 5A VCC 5B1 5B2 GND 5B3 5B4 OE3 ORDERING INFORMATION PACKAGE (1) TA (1) TOP-SIDE MARKING SN74ALVCH162344DL Tape and reel SN74ALVCH162344DLR TSSOP - DGG Tape and reel SN74ALVCH162344GR ALVCH162344 TVSOP - DGV Tape and reel SN74ALVCH162344VR VH2344 SSOP - DL -40°C to 85°C ORDERABLE PART NUMBER Tube ALVCH162344 Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.
