SN74ALVCH245DW TI Bus Transceiver | 20-SOIC | 3.3V, 8-Bit, Non-Inverting

Product Overview

The SN74ALVCH245DW is an 8-bit (octal) non-inverting bus transceiver from Texas Instruments, designed for 3.3V operation. It features two-way data flow between A and B ports, controlled by direction (DIR) and output enable (OE) inputs. The device is part of the ALVCH family, offering low-voltage operation with high drive capability and bus-hold circuitry to eliminate the need for external pull-up resistors. Housed in a 20-pin SOIC package, it is ideal for bidirectional data communication in mixed-voltage systems.
