SN54ABT853, SN74ABT853 are 8-bit to 9-bit parity bus transceivers with high reliability, low power consumption, ESD protection, and high-drive outputs.
The SN54ABT853 and SN74ABT853 are 8‑bit to 9‑bit parity bus transceivers that generate and check parity bits during data transfers between two buses. They provide true data at their outputs and include a parity‑error (ERR) flag that can be latched, sampled, stored, or cleared via dedicated control inputs.
The devices operate over a wide temperature range, offer high‑drive outputs, robust ESD protection, and latch‑up performance. Detailed electrical characteristics, absolute maximum ratings, and timing requirements are provided for design and verification.
