Nexperia 74LVC157A/74LVC157A-Q100 Quad 2-Input Multiplexers

Introduction

The Nexperia 74LVC157A/74LVC157A-Q100 Quad 2-Input Multiplexers are versatile semiconductor devices designed for efficient data source selection in various applications. With the ability to operate at both 3.3V and 5V, these multiplexers are ideal for mixed voltage environments, making them a valuable component in modern electronic designs.

Part Description

The 74LVC157A/74LVC157A-Q100 features select (S) and enable (E) inputs that allow users to choose between two data sources. When the select input (S) is HIGH, data source 1 is selected; when LOW, data source 0 is chosen. The enable input (E) can force all outputs (1Y to 4Y) LOW when set HIGH. This device is designed to handle slower input rise and fall times thanks to its Schmitt-trigger action at all inputs. Additionally, it is qualified per AEC-Q100 Grade 1, ensuring reliability in automotive applications, and operates within a temperature range of -40°C to +125°C.
