HD74HCT564/HD74HCT574

Octal D-type Flip-Flops (with 3-state outputs)

Description

These devices are positive edge triggered flip-flops. The difference between HD74HCT564 and

HD74HCT574 is only that the former has inverting outputs and the latter has non-inverting outputs.

Data at the D inputs, meeting the set-up and hold time requirements, are transferred to the Q or

outputs

on positive going transitions of the clock (CK) input. When a high logic level is applied to the output

control (OC) input, all outputs go to a high impedance state, regardless of what signals are present at the

other inputs and the state of the storage elements.

Features

•

LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility

High Speed Operation: t

(D to Q,

= 15 ns typ (C

= 50 pF)

High Output Current: Fanout of 15 LSTTL Loads

Wide Operating Voltage: V

= 4.5 to 5.5 V

Low Input Current: 1 µA max

Low Quiescent Supply Current: I

(static) = 4 µA max (Ta = 25°C)
