TECHNICAL DATA
IN74LV241
OCTAL BUFFER/LINE DRIVE; 3-STATE
The IN74LV241 is a low-voltage Si-gate CMOS device and is pin and
function compatible with IN74HC/HCT241.
The IN74LV241 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.

This device contains protection circuitry to guard against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages
to this high-impedance circuit. For proper operation, V and VOUT should be constrained to the range GND£(V or
IN
IN
VOUT)£VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.
