The Texas Instruments SN74LVC245APWR is an 8-bit bidirectional bus transceiver with 3-state outputs designed for asynchronous communication between two data buses. Direction control is provided by the DIR input, while the OE input enables or places the outputs into a high-impedance state.
The device operates from a 1.65V to 3.6V supply voltage, allowing it to interface with a wide range of low-voltage digital systems. Its inputs can accept voltages up to 5.5V, providing flexibility when interfacing devices operating at different logic levels.
The SN74LVC245A provides fast switching performance, with a maximum propagation delay of approximately 6.3ns at 3.3V. It also supports mixed-mode signal operation and includes Ioff circuitry for partial-power-down applications and live insertion protection.
With eight bidirectional channels and balanced outputs, the SN74LVC245APWR is well suited for bus buffering, signal isolation, logic interfacing, and data transfer applications in embedded, networking, industrial, and communication equipment.
The SN74LVC245APWR version is supplied in a 20-pin TSSOP (PW) package with tape-and-reel packaging, making it suitable for automated SMT assembly and high-volume production.
