SN74HC245PW Octal Bus Transceiver – Texas Instruments | High-Speed CMOS, 3-State Outputs, TSSOP-20Product Description :
The SN74HC245PW, manufactured by Texas Instruments, is a high-speed CMOS octal bus transceiver designed for bidirectional data communication on 8-bit buses. It features non-inverting, 3-state outputs, enabling easy control of data flow in both directions using a single direction (DIR) and output enable (OE) control scheme.
Operating within a 2 V to 6 V supply voltage range, the SN74HC245PW is highly versatile and suitable for a variety of logic-level systems. It offers typical propagation delays of 8–22 ns, allowing for fast and reliable data transfers while maintaining low power consumption, making it an excellent choice for battery-powered and embedded applications.
Packaged in a TSSOP-20 surface-mount case, this IC is ideal for compact designs. It belongs to the HC logic family and supports CMOS input and output levels, ensuring broad compatibility with digital circuits.
