NXP 74HC253N Dual 4-Channel Multiplexer with 3-State Outputs

The NXP 74HC253N is a high-speed Si-gate CMOS device that is part of the 74HC series. It is a dual 4-channel multiplexer featuring 3-state outputs, designed to select one of four data sources for each output. This component is particularly well-suited for applications where multiple data lines need to be routed to a single data line, such as in data bus management, signal gating, and communication systems.

Key Features

• Logic Family: The device belongs to the 74HC family, which means it has a high noise immunity and low power consumption characteristic of CMOS integrated circuits.
• Dual Multiplexer: The 74HC253N includes two independent 4-channel multiplexers, allowing for flexible routing of signals.
• 3-State Outputs: The outputs can be put in a high-impedance state, effectively disconnecting the output from the circuit, which is ideal for interfacing with bus lines in a digital system.
• Common Output Enable: A common output enable control makes it easy to control the state of all outputs simultaneously.
• Wide Operating Voltage: It operates across a wide voltage range from 2.0 to 6.0 V, compatible with various logic levels and making it suitable for interfacing with both TTL and CMOS technologies.
• High-Speed Operation: Fast switching speeds are a hallmark of the 74HC series, and the 74HC253N is no exception, ensuring minimal propagation delays.
• Standard Pin Configuration: The device comes in a standard DIP-16 package, which is easy to handle and compatible with breadboards and standard IC sockets.
