74F899

9-Bit Latchable Transceiver

with Parity Generator/Checker

General Description

Features

■ Latchable transceiver with output sink of 24 mA at the

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.

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

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.

■ 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)
