U74LVC257 - QUADRUPLE 2-LINE TO 1-LINE DATA SELECTORS/MULTIPLEXERS

General Description

The U74LVC257 is designed for 1.65V to 3.6V VCC operation.

The U74LVC257 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.

Key Features

  • S.
  • 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.
