74HC240; 74HCT240

Octal buffer/line driver; 3-state; inverting

Rev. 6 — 2 September 2021

Product data sheet

1. General description

The 74HC240; 74HCT240 is an 8-bit inverting buffer/line driver with 3-state outputs. The device

can be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE

and 2OE), each controlling four of the 3-state outputs. A HIGH on nOE 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

Complies with JEDEC standards:

•

JESD8C (2.7 V to 3.6 V)

JESD7A (2.0 V to 6.0 V)

•

Input levels:

•

For 74HC240: CMOS level

For 74HCT240: TTL level

•

Inverting 3-state outputs

ESD protection:

•

HBM JESD22-A114F exceeds 2000 V
