TECHNICAL DATA
SL74LV244
OCTAL BUFFER/LINE DRIVE; 3-STATE
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.
