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 V_CC

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
