U74LVC240
OCTAL BUFFER/DRIVER WITH
3-STATE OUTPUTS
DESCRIPTION
The U74LVC240 contains two 4-bit line drivers with separate
output-enable( OE ) inputs. When OE is low, the device passes
data from the A to the Y. When OE is high, the outputs are in the
high-impedance state.
The U74LVC240 can be used in a mixed 3.3V/5V system
environment. This device has power-down protective circuit,
preventing device destruction when it is powered down.
FEATURES
* Operate From 1.65V to 3.6V
* Input Accept Voltages to 5.5V
* Partial-Power-Down Mode Operation
* Max tpd is 5.9ns at 3.3V
