General description

The 74ABT899 is a 9-bit to 9-bit parity transceiver with separate transparent latches for the A bus and B bus. Either bus can generate or check parity. The parity bit can be fed-through with no change or the generated parity can be substituted with the SEL input.

Parity error checking of the A and B bus latches is continuously provided with ERRA and ERRB, even with both buses in 3-State.

The 74ABT899 features independent latch enables for the A and B bus latches, a select pin for ODD/EVEN parity, and separate error signal output pins for checking parity.

Features

  • Symmetrical (A and B bus functions are identical)
  • Selectable generate parity or 'feed-through' parity for A-to-B and B-to-A directions
  • Independent transparent latches for A-to-B and B-to-A directions
  • Selectable ODD/EVEN parity
  • Continuously checks parity of both A bus and B bus latches as ERRA and ERRB
  • Ability to simultaneously generate and check parity
  • Can simultaneously read/latch A and B bus data
  • Output capability: +64 mA/-32mA
  • Latch-up protection exceeds 500mA per Jedec JC40.2 Std 17
  • ESD protection exceeds 2000 V per MIL STD 883 Method 3015 and 200 V per Machine Model
  • Power up 3-State
  • Power-up reset
  • Live insertion/extraction permitted
