1. General description

The 74HC153; 74HCT153 is a dual 4-input multiplexer. The device features independent enable

inputs (nE) and common data select inputs (S0 and S1). For each multiplexer, the select inputs

select one of the four binary inputs and routes it to the multiplexer output (nY). A HIGH on E forces

the corresponding multiplexer outputs LOW. Inputs include clamp diodes. This enables the use of

current limiting resistors to interface inputs to voltages in excess of VCC.
