onsemi Logic - Specialty Logic 74ABT899CQC

The 74ABT899CQC is a 9-bit latchable transceiver designed for parity generation and checking. It operates as a feed-through transceiver or can generate/check parity from 8-bit data buses in both directions. The device features independent latch enables for A-to-B and B-to-A communication, a select pin for odd/even parity, and separate error signal output pins for parity checking. This component supports a maximum output sink of 64 mA and allows simultaneous parity generation and checking. It is compatible with various system applications, potentially replacing older components like the 543, 280, 657, and 373 without requiring changes to the transceiver. The 74ABT899CQC is available in a 28-lead plastic lead chip carrier (PLCC) package and is suitable for applications requiring reliable data integrity through parity checking.
