Quadruple 2-Line To 1-Line Data Selector/Multiplexer With 3-State Outputs

 

Description

These quadruple 2-line to 1-line data selectors and multiplexers are designed for 1.65-V to 3.6-V VCC
operation.

The SNx4LVC257A 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.

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V or 5-V system
environment.

Features

  • Operate From 1.65 V to 3.6 V
  • Inputs Accept Voltages to 5.5 V
  • Maximum tpd of 4.6 ns at 3.3 V
  • Typical VOLP (Output Ground Bounce)
    <0.8 V at VCC = 3.3 V, TA = 25°C
  • Typical VOHV (Output VOH Undershoot)
    >2 V at VCC = 3.3 V, TA = 25°C
  • Latch-Up Performance Exceeds 250 mA Per
    JESD 17
  • ESD Protection Exceeds JESD 22
    • 2000-V Human-Body Model (A114-A)
    • 200-V Machine Model (A115-A)
  • On Products Compliant to MIL-PRF-38535, All
    Parameters Are Tested Unless Otherwise Noted.
    On All Other Products, Production Processing
    Does Not Necessarily Include Testing of All
    Parameters.
