The 74HC153D is a 4-input Dual Multiplexer 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.
Non-inverting outputs
Separate enable input for each output
Common select inputs
Permits multiplexing from n lines to 1 line
Enable line provided for cascading (n lines to 1 line)
