74HC251DB-Q100数据手册集成电路（IC）的信号开关多路复用器解码器规格书PDF

描述 Description

The 74HC251-Q100; 74HCT251-Q100 is an 8-bit multiplexer with eight binary inputs (I0 to I7),three select inputs (S0 to S2) and an output enable input (OE).The select inputs select one of the eight binary inputs and route it to the complementaryoutputs (Y and Y). A HIGH on OEcauses the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes thatenable the use of current limiting resistors to interface inputs to voltages in excess ofVCC.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100(Grade 1) and is suitable for use in automotive applications.
