General Description

The 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 ACT899 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
  • 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 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
  • Standard Microcircuit Drawing (SMD) 5962-9314101
