SN54AC245, SN74AC245 is an 8-bit asynchronous bidirectional data bus transceiver produced by Texas Instruments, which can work normally in the entire military temperature range (-55°C to 125°C).
The SN54AC245 and SN74AC245 are octal bus transceivers with three‑state outputs designed for asynchronous two‑way communication between data buses. The device features a direction (DIR) pin to select data flow direction and an output‑enable (OE) pin that places the outputs in a high‑impedance state when asserted high.
The document provides detailed electrical characteristics, absolute maximum ratings, recommended operating conditions, package options, and mechanical drawings. Ordering information for various package types (PDIP, SOIC, SSOP, TSSOP, etc.) and an addendum on packaging and RoHS status are also included.
