74HC253-Q100; 74HCT253-Q100 Dual 4-input multiplexer; 3-state Rev.
4 — 27 September 2022 Product data sheet 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) an...
