74AC899 54ACT/74ACT899

9-Bit Latchable Transceiver

with Parity Generator/Checker

General Description

Features

Latchable transceiver with output sink of 24 mA

The ’AC/’ACT899 is a 9-bit to 9-bit parity transceiver with

transparent 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 ’AC/’ACT899 fea-

tures independent latch enables for the A-to-B direction and

the B-to-A direction, a select pin for ODD/EVEN parity, and

separate 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 direc-

tions

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)

4 kV minimum ESD immunity
