Product Overview: 74HC153DR2 Dual 4-Input Multiplexer from NXP

The 74HC153DR2 is a high-performance integrated circuit designed and manufactured by NXP Semiconductors. This versatile component is a dual 4-input multiplexer that is part of the 74HC (High-Speed CMOS) family of logic devices. The device is widely used in digital systems where it is necessary to select one line of data from multiple input sources.

Key Features

• Logic Type: Dual 4-Input Multiplexer
• Operating Voltage: 2 V to 6 V, accommodating a variety of logic level requirements and ensuring compatibility with both TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor) technologies.
• High-Speed Performance: The 74HC153DR2 is characterized by its fast switching speeds, which is essential for high-performance digital circuits.
• Low Power Consumption: Despite its high-speed capabilities, the device maintains low power dissipation, making it suitable for power-sensitive applications.
• Output Drive Capability: Capable of driving up to 10 LSTTL (Low-Power Schottky TTL) loads, which means it can directly drive numerous standard logic inputs.
• Schmitt Trigger Action: The multiplexer inputs include Schmitt trigger action, allowing it to smoothly handle slow input transition signals and provide noise immunity.

Functional Description

The 74HC153DR2 contains two individual 4-input multiplexers with common select inputs and separate enable inputs. Each multiplexer has four binary control inputs (A, B, C, and D) and two binary addressing inputs (S0 and S1). The binary addressing inputs determine which of the four data inputs is connected to the output. An additional enable input (E) when low, activates the multiplexer, and when high, disables the multiplexer to a high-impedance state (off-state).

Package and Quality

This multiplexer is offered in an SOIC-16 package, which is a small outline package with 16 pins, making it suitable for space-constrained applications. The 74HC153DR2 is also compliant with RoHS (Restriction of Hazardous Substances) standards, ensuring that it meets the environmental and safety standards for electronic components.

The 74HC153DR2 from NXP is a reliable and efficient solution for designers looking to perform data selection or multiplexing functions in their digital systems. Its combination of high-speed operation, low power consumption, and robust packaging makes it an excellent choice for a wide range of applications in computing, communication, and consumer electronics.
