General description

The 74HC/HCT574 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.

The 74HC/HCT574 are octal D-type flip-flops featuring separate D-type inputs for each flip-flop and non-inverting 3-state outputs for bus oriented applications. A clock (CP) and an output enable (OE) input are common to all flip-flops.

The 8 flip-flops will store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH CP transition.
When OE is LOW, the contents of the 8 flip-flops are 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 '574' is functionally identical to the '564', but has non-inverting outputs.
The '574' is functionally identical to the '374', but has a different pinning.

Features

3-state non-inverting outputs for bus oriented applications
8-bit positive edge-triggered register
Common 3-state output enable input
Independent register and 3-state buffer operation
Output capability: bus driver
I_CC category: MSI
