TECHNICAL DATA
IN74LV244
OCTAL BUFFER/LINE DRIVE; 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 by the output enable inputs 1OE and 2OE. A HIGH on nOE causes the outputs to assume a high impedance OFF-state. The IN74LV244 is identical to the IN74LV240 but has non-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 Output Current: 8 mA at VCC = 3.0 V High Noise Immunity Characteristic of
CMOS Devices
