74HC251D Datasheet | Nexperia

description The 74HC251; 74HCT251 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 plementary 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. 2. Features and benefits - Wide supply voltage range from 2.0 V to 6.0 V - CMOS low power dissipation - High noise immunity - Latch-up performance exceeds 100 m A per JESD 78 Class II Level B - plies with JEDEC standards: - JESD8C (2.7 V to 3.6 V) - JESD7A (2.0 V to 6.0 V) - Input levels: - For 74HC251: CMOS level - For 74HCT251: TTL level - Non-inverting data path - ESD protection: - - HBM JESD22-A114F exceeds 2000 V - MM JESD22-A115-A exceeds 200 V - Specified from -40 °C to +85 °C and from -40 °C to +125 °C 3.
