74HCT257PW

74HC257; 74HCT257 Quad 2-input multiplexer; 3-state Rev. 8 — 9 February 2021 Product data sheet 1. General description The 74HC257; 74HCT257 is a quad 2-input multiplexer with 3-state outputs. Inputs include clamp diodes. This enables 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 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) Non-inverting data path 3-state outputs interface directly with system bus Input levels: For 74HC257: CMOS level For 74HCT257: TTL level 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.
