M74HCT245TTR ST Bus Transceiver | 20-TSSOP | 8-Bit, Non-Inverting, 4.5V-5.5V

Product Overview

The M74HCT245TTR is an advanced high-speed CMOS octal bus transceiver from STMicroelectronics, designed for bidirectional asynchronous communication between two data buses. Fabricated with silicon gate C2MOS technology, it offers high noise immunity and low power consumption. The device features non-inverting 3-state outputs and operates from a 4.5V to 5.5V supply voltage. Housed in a compact 20-TSSOP package, it is ideal for space-constrained applications requiring reliable data transfer.
