INTEGRATED CIRCUITS 74LVC574A Octal D-type flip-flop with 5-volt tolerant inputs/outputs; positive edge-trigger (3-State) Product specification       1998 Jul 29 Philips Semiconductors Product specification Octal D-type flip-flop with 5-volt tolerant inputs/outputs; positive edge-trigger (3-State) 74LVC574A Inputs can be driven from either 3.3V or 5V devices. In 3-State operation, outputs can handle 5V. This feature allows the use of these devices as translators in a mixed 3.3V/5V environment. FEATURES • 5-volt tolerant inputs/outputs, for interfacing with 5-volt logic • Supply voltage range of 2.7V to 3.6V • Complies with JEDEC standard no. 8-1A • Inputs accept voltages up to 5.5V • CMOS low power consumption • Direct interface with TTL levels • High impedance when VCC = 0V • 8-bit positive edge-triggered register • Independent register and 3-State buffer operation • Flow-through pin-out architecture The 74LVC574A is an octal D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-State outputs for bus-oriented applications. A clock (CP) and an output enable (OE) input are common to all flip-flops. The eight flip-flops will store the state of their individual D-inputs that meet the setup and hold times requirements on the LOW-to-HIGH CP transition. When OE is LOW, the contents of the eight flip-flops is available at the outputs. When OE is HIGH, the outputs go to the high impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops. The ’574A’ is functionally identical to the ’374A’, but the ’374A’ has a different pin arrangement. DESCRIPTION The 74LVC574A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. QUICK REFERENCE DATA GND = 0V; Tamb =25°C; tr = tf  2.5ns PARAMETER SYMBOL CONDITIONS CL = 50pF VCC = 3.3V TYPICAL UNIT tPHL/tPLH Propagation delay CP to Qn fmax maximum clock frequency 150 MHz CI Input capacitance 5.0 pF CPD Power dissipation capacitance per flip-flop 20 pF 4.8 Notes 1 and 2 ns NOTE: 1. CPD is used to determine the dynamic power dissipation (PD in W): PD = CPD x VCC2 x fi +  (CL x VCC2 x fo) where: fi = input frequency in MHz; CL = output load capacity in pF; fo = output frequency in MHz; VCC = supply voltage in V;  (CL x VCC2 x fo) = sum of outputs. 2.
