SN74HCT245DGSR TI Bus Transceiver | 20-VSSOP | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74HCT245DGSR is a high-performance octal bus transceiver from Texas Instruments, designed for asynchronous bidirectional communication between data buses. It features 8-bit non-inverting buffers with 3-state outputs, enabling efficient data flow control in mixed-voltage systems. Housed in a compact 20-VSSOP package, this device operates over a wide supply voltage range of 4.5V to 5.5V, making it ideal for 5V logic environments. With TTL-compatible inputs and CMOS outputs, it bridges legacy and modern logic families seamlessly.
