1. General description
The 74HC253-Q100; 74HCT253-Q100 is a dual 4-bit multiplexer, each with four binary inputs
(nI0 to nI3), an output enable input (nOE) and shared select inputs (S0 and S1). One of the four
binary inputs is selected by the select inputs and routed to the output nY. A HIGH on nOE causes
the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables the
use of current limiting resistors to interface inputs to voltages in excess of VCC.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100
(Grade 1) and is suitable for use in automotive applications.
