ON Semiconductor MC74VHCT139ADTR2 Dual 2-to-4 Decoder/Demultiplexer

The MC74VHCT139ADTR2 is a high-performance, dual 2-to-4 decoder/demultiplexer integrated circuit produced by ON Semiconductor. This versatile component is designed to offer high-speed operation while maintaining the CMOS low power dissipation. It is particularly well-suited for implementation in memory decoding or data routing applications where high speed and low power are required.

Constructed with advanced silicon gate CMOS technology, the MC74VHCT139ADTR2 provides a robust solution for digital systems. It has two individual 2-to-4 decoders, each with an address input (nA, nB), an active-low enable input (nG), and four mutually exclusive outputs (nY0 to nY3). When the enable input is held high, all outputs remain in a low state. Conversely, when the enable input is active-low, the binary value presented at the address inputs determines which single output will transition to a high state, leaving the rest low.

The device is compatible with TTL levels, allowing it to be used in mixed-voltage systems. This feature is particularly beneficial for designers looking to integrate the device into legacy systems without the need for level shifting. The MC74VHCT139ADTR2 operates over a broad voltage range from 2.0V to 5.5V, providing designers with flexibility in various applications and ensuring compatibility with both 3.3V and 5V systems.

With its fast propagation delay and high noise immunity, the MC74VHCT139ADTR2 is an excellent choice for high-speed data processing and communication systems. It is available in a TSSOP-16 package, which is ideal for space-constrained applications. The device also features a flow-through pinout, which simplifies PCB layout by allowing inputs to be connected directly to outputs on the adjacent side of the package.

ON Semiconductor's commitment to quality ensures that the MC74VHCT139ADTR2 meets stringent standards, providing reliable performance in a wide range of operating conditions. Whether used in computer systems, instrumentation, or consumer electronics, this dual decoder/demultiplexer is an efficient solution for complex digital logic operations.
