54ACTQ646

Quiet Series Octal Transceiver/Register with 3-STATE

Outputs

General Description

Features

n Guaranteed simultaneous switching noise level and

dynamic threshold performance

The ACTQ646 consist of registered bus transceiver circuits,

with outputs, D-type flip-flops, and control circuitry providing

multiplexed transmission of data directly from the input bus

or from the internal storage registers. Data on the A or B bus

will be loaded into the respective registers on the

LOW-to-HIGH transition of the appropriate clock pin (CPAB

or CPBA). The four fundamental handling functions available

are illustrated in Figures 1, 2, 3, 4.

n Independent registers for A and B busses

n Multiplexed real-time and stored data transfers

n 300 mil slim dual-in-line package

n Outputs source/sink 24 mA

n Faster prop delays than the standard AC/ACT646

n 4 kV minimum ESD immunity

The ACTQ utilizes FSC Quiet Series technology to guaran-

tee quiet output switching and improved dynamic threshold

n Standard Microcircuit Drawing (SMD) 5962-9219601

performance. FACT Quiet Series features GTO output

control and undershoot corrector in addition to a split ground

bus for superior performance.
