IN74LV244

OCTAL BUFFER/LINE DRIVER 3-STATE

The IN74LV244 is a low-voltage Si-gate CMOS device and is pin and function compatible with

IN74HC/HCT244.

The IN74LV244 is an octal non-inverting buffer/line

driver with 3-state outputs. The 3-state outputs are controlled

causes the outputs to assume a high impedance OFF-state.

The IN74LV244 is identical to the IN74LV240 but has non-

inverting outputs.

DW SUFFIX

• 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

• Output Current: 8 mA at V_CC= 3.0 V
