TECHNICAL DATA
OCTAL BUFFER/LINE DRIVE; 3-STATE
SL74LV244
The SL74LV244 is a low-voltage Si-gate CMOS device and is pin and
function compatible with SL74HC/HCT244.
The SL74LV244 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 SL74LV244 is identical to the SL74LV240 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 µÀ at Ò = 25 °Ñ
• Output Current: 8 mA at VCC = 3.0 V
• High Noise Immunity Characteristic of CMOS Devices
