GENERAL 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 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 Log...
