74HC251-Q100; 74HCT251-Q100 8-input multiplexer; 3-state Rev. 2 — 15 July 2019 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 VCC. 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 Input levels: • For 74HC251-Q100: CMOS level • For 74HCT251-Q100: TTL level Low-power dissipation Non-inverting data path Specified in compliance with JEDEC standard no. 7A 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 Ω) Multiple package options 3.
