16-Bit Transceiver/Register with 3-STATE Outputs

General Description

Features

The ACTQ16646 contains sixteen non-inverting bidirec-

tional registered bus transceivers providing multiplexed

transmission of data directly from the input bus or from the

internal storage registers. Each byte has separate control

inputs which can be shorted together for full 16-bit opera-

tion. The DIR inputs determine the direction of data flow

through the device. The CPAB and CPBA inputs load data

into the registers on the LOW-to-HIGH transition. The

ACTQ16646 utilizes Fairchild Quiet Series technology to

guarantee quiet output switching and improved dynamic

■ Utilizes Fairchild FACT Quiet Series technology

■ Guaranteed simultaneous switching noise level and

dynamic threshold performance

■ Guaranteed pin-to-pin output skew

■ Independent registers for A and B buses

■ Multiplexed real-time and stored data transfers

■ Separate control logic for each byte

■ 16-bit version of the ACTQ646

■ Outputs source/sink 24 mA

■ Additional specs for Multiple Output Switching

■ Output loading specs for both 50 pF and 250 pF loads

GTO output control and undershoot corrector for superior

performance.
