DESCRIPTION
SOP-16
The U74LVC258 is designed for 1.65V to 3.6V VCC operation.
The U74LVC258 devices are designed to multiplex signals from
4-bit data sources to 4-output data lines in bus-organized systems.
The 3-state outputs do not load the data lines when the
output-enable ( OE ) input is at a high logic level.

FEATURES
* Operate From 1.65V to 3.6V
* Input Accept Voltages to 5.5V
* Partial-Power-Down Mode Operation
* Max tpd is 4.6ns at 3.3V
