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.
The document describes the NXP 74HC153 and 74HCT153 as a dual 4-input multiplexer featuring independent enable inputs (nE) and common data select inputs (S0 and S1). The device routes one of four binary inputs to the output based on the select lines, with a HIGH signal on the enable input forcing the outputs LOW. It includes clamp diodes on inputs to allow interfacing with voltages in excess of VCC using current-limiting resistors.
