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

• 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)
