Texas Instruments CD74AC151 8-Input Data Selector/Multiplexer

Introduction

The Texas Instruments CD74AC151 is a versatile 8-input data selector/multiplexer designed to efficiently route data from multiple sources. With its ability to operate within a voltage range of 1.5V to 5.5V, this component is ideal for various applications in digital circuits.

Part Description

The CD74AC151 provides full binary decoding to select one of eight data sources, making it a powerful tool for data routing and selection. It features a strobe input (G) that must be at a low logic level to enable the inputs. When the strobe is high, the W output goes high while the Y output goes low. This multiplexer boasts balanced noise immunity at 30% of the supply voltage, ensuring reliable performance in noisy environments. It also supports a drive current of ±24mA with a fanout to 15 F devices, making it suitable for a wide range of applications.
