NXP 74HC258N Quad 2-input multiplexer with tri-state outputs

The NXP 74HC258N is a high-speed Si-gate CMOS device that is part of the 74HC family. This quad 2-input multiplexer features tri-state outputs which are essential for bus-oriented applications. The device comes in a standard DIP-16 (Dual In-line Package) making it suitable for breadboard prototyping and traditional through-hole PCB designs.

Key Features

• Logic Type: Quad 2-Input Multiplexer
• Output Type: Tri-State
• Package Type: DIP-16
• Supply Voltage Range: 2.0V to 6.0V
• Operating Temperature Range: -40°C to +125°C
• Pin Configuration: The 74HC258N has a 16-pin configuration with input, output, enable, and supply voltage pins.
• High Noise Immunity: The device incorporates high noise immunity characteristics typical of CMOS devices.

Functional Description

The 74HC258N contains four independent 2-input multiplexers with tri-state outputs. Each multiplexer has two data inputs (A and B), one common data select input (S), and one output (Y). The tri-state control input (G) can be used to place the output in a high-impedance state. When the select input (S) is held at a low level, the A input is connected to the Y output, and when S is high, the B input is connected to the Y output. The tri-state outputs allow multiple outputs to be connected to a common bus without interference.

Applications

The 74HC258N is ideal for multiplexing and data routing applications. It can be used in a variety of systems including:

• Bus switching and resource allocation
• Data routing in microprocessor or microcontroller-based systems
• Signal gating and processing
• Function generation
• Control systems

With its robust design and versatile functionality, the NXP 74HC258N is a valuable component for designers looking for a reliable multiplexer solution.
