74HC251-Q100 74HCT251-Q100 8-input multiplexer 3-state Rev. 3 8 February 2021 Product data sheet 1. General 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 complementary outputs (Y and Y). A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of V . CC This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications. 2. Features and benefits Automotive product qualification in accordance with AEC-Q100 (Grade 1) Specified from -40 C to +85 C and from -40 C to +125 C Wide supply voltage range from 2.0 V to 6.0 V CMOS low power dissipation High noise immunity Latch-up performance exceeds 100 mA per JESD 78 Class II Level B Complies with JEDEC standards: JESD8C (2.7 V to 3.6 V) JESD7A (2.0 V to 6.0 V) Input levels: For 74HC251-Q100: CMOS level For 74HCT251-Q100: TTL level Non-inverting data path ESD protection: MIL-STD-883, method 3015 exceeds 2000 V HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V (C = 200 pF, R = 0 ) 3.
