SN74HC258 (ACTIVE) Quadruple 2-Line To 1-Line Data Selectors/Multiplexers With 3-State Outputs

Quadruple 2-Line To 1-Line Data Selectors/Multiplexers With 3-State Outputs - SN74HC258
Datasheet
 

Description

These 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 (G\) input is at a high logic level.

To ensure the high-impedance state during power up or power down, (G\) should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

Features

  • Wide Operating Voltage Range of 2 V to 6 V
