9-Bit Latchable Transceiver with Parity

Generator/Checker

General Description

Features

■ Latchable transceiver with output sink of 24 mA

The ACT899 is a 9-bit to 9-bit parity transceiver with trans-

parent latches. The device can operate as a feed-through

transceiver or it can generate/check parity from the 8-bit

data busses in either direction. The ACT899 features inde-

pendent latch enables for the A-to-B direction and the B-to-

A direction, a select pin for ODD/EVEN parity, and sepa-

rate error signal output pins for checking parity.

■ Option to select generate parity and check or

“feed-through” data/parity in directions A-to-B or B-to-A

■ Independent latch enable for A-to-B and B-to-A

directions

■ Select pin for ODD/EVEN parity

■ ERRA and ERRB output pins for parity checking

■ Ability to simultaneously generate and check parity

■ May be used in system applications in place of the 280

■ May be used in system applications in place of the 657

and 373 (no need to change T/R to check parity)
