DUAL BUS BUFFER GATE
WITH 3-STATE OUTPUTS
DESCRIPTION
The U74LVC2G125L consists of two bus buffers with 3-state
output controlled by enable input (nOE), when nOE is high, the
output is disable.
MSOP-8
Inputs can be driven from either 3.3V or 5V devices, so the
device can be used in a mix 3.3V/5V system.
This device is full specified for partial power-down protective
circuit, preventing the backflow current through the device when
it is powered down.
TSSOP-8
FEATURES
* Operation Voltage Range: 1.65~5.5V
* Low Power Dissipation
* Input Accept Voltage to 5.5V
