Product Overview: 74HC158 - Quad 2-Input Multiplexer from NXP Semiconductors

The 74HC158 is a high-speed Si-gate CMOS device from NXP Semiconductors and is part of the 74HC series. This integrated circuit is designed to function as a quad 2-input multiplexer with common select and enable inputs. It is a versatile component that can be used in a wide array of digital applications, including data routing, signal gating, and function generation.

Key Features

• Logic Type: Quad 2-Input Multiplexer
• Supply Voltage Range: 2.0 to 6.0 V
• High Noise Immunity: NIV = VNIH = VNIL = 28% VCC (min)
• Low Power Dissipation: ICC = 4 µA (max) @ Ta = 25°C
• High-Speed Performance: tpd = 13 ns (typ) @ VCC = 5 V, CL = 15 pF, Ta = 25°C
• Output Drive Capability: 10 LSTTL Loads
• Pin and Function Compatibility: With 74 series 158

Functional Description

The 74HC158 consists of four identical 2-input multiplexers which select one of the two binary inputs based on the state of the common select input (S) and present the chosen input at the output. An additional enable input (E\) is used to disable the output and force it into a high-impedance state. When E\ is held high, the outputs are disabled regardless of the other inputs.

Applications

The flexibility of the 74HC158 makes it suitable for a variety of digital applications, including:

• Function generation
• Data routing and multiplexing
• Signal gating
• Control logic
• Computer memory address decoding
