SN74LVCH8T245NSR TI Bus Transceiver | 24-SO | 8-bit, Dual Supply, Voltage Level Translation

Product Overview

The SN74LVCH8T245NSR is a high-performance 8-bit bus transceiver from Texas Instruments, designed for voltage level translation in mixed-voltage systems. It operates with dual supply voltages (VCCA and VCCB) ranging from 1.65V to 5.5V, enabling seamless communication between different voltage domains. The device features non-inverting data paths, direction control (DIR), and output enable (OE) for flexible bus management. Housed in a 24-pin SO package, it is ideal for space-constrained applications requiring bidirectional data flow.
