onsemi Voltage Level Shifter Bus Transceiver 1 TTL/NMOS, 20-Pin SOIC MC74HCT245ADWG

The onsemi MC74HCT245ADWG is a voltage level shifter bus transceiver designed with high-performance silicon-gate CMOS technology. It is optimized for bi-directional translation between TTL or NMOS output levels and High Speed CMOS inputs, making it a versatile component for digital logic interfacing.

This device features a 3-state noninverting transceiver architecture which enables two-way asynchronous communication between data buses. The active-low Output Enable pin allows the I/O ports to be placed into a high-impedance state, preventing bus contention during device disablement. Direction control selects the data flow direction, either from A to B or B to A.

It provides output drive capable of 15 LSTTL loads and accepts input levels compatible with TTL, NMOS, and CMOS logic families. The MC74HCT245ADWG operates within a voltage range of 4.5 to 5.5 volts and maintains low input current consumption of 1.0 mA. With a maximum propagation delay time of 42 ns at a given capacitive load, it is suitable for timing-sensitive applications.

The device is housed in a compact 20-pin Surface Mount SOIC package with a length of 12.95 mm and height of 2.4 mm. It supports a wide operating temperature range from -55°C to 125°C, allowing for use in harsh industrial environments.

Typical use cases include industrial control systems, electronic equipment, and consumer devices requiring voltage translation and bus transceiver functionality. This component allows seamless interfacing between logic families and enhances signal integrity in digital communication circuits.
