DM74LS564

Octal D-Type Flip-Flop with TRI-STATE Outputs

General Description

Features

Inputs and outputs on opposite sides of package allow-

ing easy interface with microprocessors

The ’LS564 is a high speed low power octal flip-flop with a

buffered common Clock (CP) and a buffered common Out-

put Enable (OE). The information presented to the D inputs

is stored in the flip-flops on the LOW-to-HIGH Clock (CP)

transition

Useful as input or output port for microprocessors

Functionally identical to ’LS574

Input clamp diodes limit high speed termination effects

Fully TTL and CMOS compatible

This device is functionally identical to the ’LS574, but has

inverted outputs. For complete discussions of operations,

truth tables, AC and DC electrical specifications, refer to the

’LS374 data sheet.
