ON Semiconductor MC74LCX139DT Dual 2-to-4 Line Decoder/Demultiplexer

The MC74LCX139DT from ON Semiconductor is a high-performance, dual 2-to-4 line decoder/demultiplexer integrated circuit designed for use in a wide range of digital applications. This device is part of the LCX family, which is known for its low voltage operation and compatibility with LVTTL and LVCMOS technologies.

Constructed with advanced silicon gate CMOS technology, the MC74LCX139DT provides a robust and reliable solution for systems that require efficient decoding or demultiplexing of signals. It is particularly suitable for memory decoding or data-routing applications, where it can efficiently manage address and data signals to different parts of a system.

Each decoder in the MC74LCX139DT has two select inputs (A and B), an enable input (E\), and four mutually exclusive outputs (Y0 to Y3). When the enable input is held high, all outputs are forced low. Conversely, when the enable input is active low, the selected output corresponding to the combination of the A and B inputs is driven low, while the remaining outputs stay high.

Key features of the MC74LCX139DT include:

• 5V tolerant inputs, allowing interface with 5V logic levels
• Low static and dynamic power consumption, making it ideal for power-sensitive applications
• High-speed operation, with a typical t_PD of 5.3ns at V_CC = 3.3V
• Power-down high impedance inputs and outputs, ensuring minimal leakage when the device is not in use
• Support for mixed-mode signal operation, enabling it to interface with both 3.3V and 5V logic levels

The MC74LCX139DT is available in a TSSOP-16 package, providing a compact footprint for space-constrained applications. Its operating temperature range of -40°C to +85°C ensures reliable performance across a broad spectrum of environmental conditions.

Whether you're designing consumer electronics, communication systems, or computer peripherals, the ON Semiconductor MC74LCX139DT offers a versatile and efficient solution for your decoding and demultiplexing needs, backed by the quality and reliability of a leading semiconductor manufacturer.
