74HCT540

74HC540; 74HCT540 Octal buffer/line driver; 3-state; inverting Rev. 6 — 19 October 2021 Product data sheet 1. General 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 mA per JESD 78 Class II Level B Inverting outputs Input levels: For 74HC540: CMOS level For 74HCT540: TTL level Complies 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.
