74F899 - Fairchild

74F899 9-Bit Latchable Transceiver

The 74F899 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. It has a guaranteed current sinking capability of 24 mA at the A-bus and 64 mA at the B-bus. The 74F899 features independent latch enables for the A-to.

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.
