1. General description
The 74HCT534 is a high-speed Si-gate CMOS device and is pin compatible with low
power Schottky TTL (LSTTL). The 74HCT534 is specified in compliance with JEDEC
standard no. 7A.
The 74HCT534 is an octal D-type flip-flop featuring separate D-type inputs for each
flip-flop and 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
times 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 74HCT534 is functionally identical to the 74HCT374, but has inverted outputs.
2. Features
3-state inverting outputs for bus oriented applications
8-bit positive-edge triggered register
Common 3-state output enable input.

[3] For data sheets describing multiple type numbers, the highest-level product status determines the data sheet status.
16. Definitions
Short-form specification — The data in a short-form specification is
extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with
the Absolute Maximum Rating System (IEC 60134). Stress above one or
more of the limiting values may cause permanent damage to the device.
These are stress ratings only and operation of the device at these or at any
other conditions above those given in the Characteristics sections of the
specification is not implied. Exposure to limiting values for extended periods
may affect device reliability.
Application information — Applications that are described herein for any
of these products are for illustrative purposes only. Philips Semiconductors
make no representation or warranty that such applications will be suitable for
the specified use without further testing or modification.
