SN74LVCH245APWT TI Bus Transceiver | 20-TSSOP | 3.3V, 8-Bit, Non-Inverting

Product Overview

The SN74LVCH245APWT from Texas Instruments is a high-performance 8-bit bus transceiver designed for 3.3-V operation. It features non-inverting 3-state outputs and is part of the LVC family, offering low-voltage operation with high drive capability. The device is housed in a 20-pin TSSOP package, making it suitable for space-constrained applications. It supports bidirectional data flow between two buses (A and B) controlled by the direction control (DIR) and output enable (OE) inputs. The SN74LVCH245APWT is ideal for interfacing between different voltage domains or for driving heavily loaded backplanes.
