ON Semiconductor MC74VHCT138ADTRG Decoder/Demultiplexer

The MC74VHCT138ADTRG is a high-performance, integrated circuit from ON Semiconductor, designed to function as a 3-to-8 line decoder or demultiplexer. This versatile component is part of the high-speed CMOS VHCT family and is fabricated with silicon gate CMOS technology, which ensures reduced power consumption while maintaining high-speed operation.

Featuring a trio of binary select inputs (A, B, and C), the MC74VHCT138ADTRG can decode a binary code to one of eight mutually exclusive outputs. The device is equipped with three enable inputs: two active-low (E1, E2) and one active-high (E3). The outputs are designed to provide a high-level signal only when the binary value on the select inputs matches the output number, and all the enable inputs are activated. This precise control makes the device ideal for a wide range of applications, including hardware programming, address decoding for memory and I/O, and the simplification of multiple-input logic designs.

One of the key features of the MC74VHCT138ADTRG is its compatibility with TTL levels. This allows the device to be used in systems incorporating both CMOS and TTL logic, providing designers with a versatile solution for mixed-logic environments. Moreover, the device's high noise immunity and low power dissipation make it suitable for use in noisy or power-sensitive applications.

The MC74VHCT138ADTRG comes in a TSSOP-16 package, which is compact and suitable for surface-mount technology (SMT), thereby saving precious board space. The device operates over a broad voltage range from 4.5V to 5.5V, making it adaptable to various operating conditions and ensuring compatibility with standard 5V systems.

ON Semiconductor's commitment to quality ensures that the MC74VHCT138ADTRG meets stringent standards, providing reliable performance in a wide array of electronic systems, from consumer electronics to industrial automation. By choosing the MC74VHCT138ADTRG, designers and engineers can be confident in delivering efficient and effective solutions for complex digital logic tasks.
