Product specification
74HC/HCT564
FEATURES
3-state 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
ICC category: MSI
GENERAL DESCRIPTION
The 74HC/HCT564 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/HCT564 are octal D-type flip-flops 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 “564” is functionally identical to the “574” but has
inverting outputs. The “564” is functionally identical to the
“534”, but has a different pinning.

Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW):
PD = CPD × VCC2 × fi +(CL × VCC2 × fo) where:
fi = input frequency in MHz
fo = output frequency in MHz
(CL × VCC2 × fo) = sum of outputs
CL = output load capacitance in pF
VCC = supply voltage in V
2. For HC the condition is VI = GND to VCC; for HCT the condition is VI = GND to VCC 1.5 V
