TECHNICAL DATA

KK74LV240

OCTAL BUFFER/LINE DRIVE; 3-STATE

The

KK74LV240 is a low-voltage Si-gate CMOS device and is pin and

function compatible with

KK74HC/HCT240.

The

KK74LV240 is an octal non-inverting buffer/line driver with 3-state

outputs. The 3-state outputs are controlled by the output enable inputs 1OE

and 2OE. A HIGH on nOE causes the outputs to assume a high impedance

OFF-state.

The

KK74LV240 is identical to the KK74LV244 but has inverting

outputs.

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 1.2 to 3.6 V

• Low Input Current: 1.0 µA, 0.1 µА at Т = 25 °С

• High Noise Immunity Characteristic of CMOS Devices
