( Top View )
The 74LVC2G34 is a dual buffer gate with standard push-pull outputs.
( Top View )
The device is designed for operation with a power supply range of
6
1A 1 1Y
1.65V to 5.5V. The inputs are tolerant to 5.5V allowing this device to
1A 1 6 1Y
be used in a mixed voltage environment. The device is fully specified
