Product Overview: 74HCT139PW,118

The 74HCT139PW,118 is a high-speed Si-gate CMOS device that is part of NXP Semiconductors' 74HCT family. This integrated circuit is designed to provide users with a dual 2-to-4 line decoder/demultiplexer with a wide range of applications in digital systems. The chip is characterized by its low power consumption and high noise immunity, making it suitable for interfacing with TTL levels.

Key Features

• Logic Family: 74HCT
• Logic Type: Dual 2-to-4 Line Decoder/Demultiplexer
• Package Type: TSSOP
• Pin Count: 16
• Supply Voltage Range: 4.5V to 5.5V
• Operating Temperature Range: -40°C to +125°C

Functional Description

The device features two individual 2-to-4 decoders, each with an active LOW enable input (nE). When the enable input is held high, the decoder outputs remain low. When the enable input is active, each decoder converts the binary weighted inputs (nA0, nA1) to one of four mutually exclusive outputs (nY0 to nY3). The 74HCT139PW,118 is designed to be used in high-performance memory-decoding or data-routing applications requiring very short propagation delay times.

Applications

Due to its versatility and performance characteristics, the 74HCT139PW,118 is ideal for a variety of applications, including:

• Memory decoding
• Data routing
• Control logic
• Computers and computer peripherals
• Instrumentation
