Quiet Series¥ Octal Bidirectional Transceiver

with 3-STATE Inputs/Outputs

General Description

Features

■ I_CCand I_OZreduced by 50%

The ACQ/ACTQ245 contains eight non-inverting bidirec-

tional buffers with 3-STATE outputs and is intended for bus-

oriented applications. Current sinking capability is 24 mA at

both the A and B ports. The Transmit/Receive (T/R) input

determines the direction of data flow through the bidirec-

tional transceiver. Transmit (active-HIGH) enables data

from A Ports to B Ports; Receive (active-LOW) enables

data from B Ports to A Ports. The Output Enable input,

when HIGH, disables both A and B ports by placing them in

a HIGH Z condition.

■ Guaranteed simultaneous switching noise level and

dynamic threshold performance

■ Guaranteed pin-to-pin skew AC performance

■ Improved latch-up immunity

■ 3-STATE outputs drive bus lines or buffer memory

address registers

■ Outputs source/sink 24 mA

■ Faster prop delays than the standard ACT245

The ACQ/ACTQ utilizes Fairchild Quiet Series technol-

ogy to guarantee quiet output switching and improve

dynamic threshold performance. FACT Quiet Series fea-

tures GTO output control and undershoot corrector in

addition to a split ground bus for superior performance.
