74HCT540 Datasheet | Nexperia

description The 74HC540; 74HCT540 is an 8-bit inverting buffer/line driver with 3-state outputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes the outputs to assume a high-impedance OFF-state. 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 m A per JESD 78 Class II Level B - Inverting outputs - Input levels: - For 74HC540: CMOS level - For 74HCT540: TTL level - plies with JEDEC standards - JESD8C (2.7 V to 3.6 V) - JESD7A (2.0 V to 6.0 V) - ESD protection: - HBM JESD22-A114F exceeds 2000 V - MM JESD22-A115-A exceeds 200 V - Multiple package options - Specified from -40 °C to +85 °C and from -40 °C to +125 °C 3.
