Product details

Description

The ’AC ’ACT899 is a 9-bit to 9-bit parity transceiver with transparent latches The device can operate as a feedthrough transceiver or it can generate check parity from the 8-bit data busses in either direction The ’AC ’ACT899 feawww.DataSheet4U.com 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

Features

Y Y Y Y Y Y Y Y Y Latchable transceiver with output sink of 24 mA Option to select generate parity and check or ‘‘feedthrough’’ 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.
