SN74AHCT245DWR TI Buffers, Drivers, Receivers, Transceivers

The SN74AHCT245 is an octal bus transceiver with 3-state outputs for bidirectional bus communication, operating from 4.5V to 5.5V supply. It features TTL-compatible input thresholds for direct interfacing with TTL logic while providing CMOS output levels. The device includes a direction control (DIR) pin that determines data flow (A to B or B to A) and an output enable (OE) pin that disables both ports for bus isolation. High drive capability supports bus driving without external components. Propagation delay is 7.2ns typical at 5V. Selection is standard for 5V mixed TTL/CMOS bus systems requiring bidirectional data transfer. Applications include microprocessor data bus expansion, memory interfacing, peripheral communication in industrial controls, computing equipment, and automotive electronics requiring 8-bit bidirectional bus transceiver.
