74F899 9-Bit Latchable Transceiver

February 1989

Revised August 1999

74F899

9-Bit Latchable Transceiver

with Parity Generator/Checker

General Description

The 74F899 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. It has a guaranteed current

sinking capability of 24 mA at the A-bus and 64 mA at the

B-bus.

The 74F899 features 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.

Features

Latchable transceiver with output sink of 24 mA at the

A-bus and 64 mA at the B-bus

Option to select generate parity and check or

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

Independent latch enables 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 systems applications in place of the

74F543 and 74F280

May be used in system applications in place of the

74F657 and 74F373 (no need to change T/R to check

parity)
