Rev. 03 — 18 October 2004
Product data sheet
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.

CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;

CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in Volts;
N = number of inputs switching;
Σ(CL × VCC2 × fo) = sum of the outputs.

The condition is VI = GND to VCC − 1.5 V.
