Texas Instruments Buffers, Drivers, Receivers, Transceivers SN74ALS29854NT

The SN74ALS29854NT is an 8-bit to 9-bit parity bus transceiver designed for two-way communication between data buses. It features a parity generator and checker, which generates a parity bit during data transmission from the A bus to the B bus. The device includes an open-collector parity-error flag (ERR) that indicates whether an error has occurred in the B data when it is transmitted back to the A bus. The output-enable inputs (OEA, OEB) allow for bus isolation when the device is disabled. This transceiver supports various operational modes, including data transfer with parity generation and error checking, as well as the ability to store and clear the parity-error flag using control inputs. It operates within a temperature range of 0¬8C to 70¬8C and is available in a 24-pin plastic dual in-line package (PDIP). The SN74ALS29854 is functionally similar to AMD's AM29854, providing compatibility for designs that require parity checking in data communication systems.
