INTEGRAL
OCTAL BUFFER/LINE DRIVE; 3-STATE
The IN74LV240 is a low-voltage Si-gate CMOS device and is pin and
function compatible with IN74HC/HCT240.
The IN74LV240 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 IN74LV240 is identical to the IN74LV244 but has inverting
outputs.
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 1.2 to 3.6 V
