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.
- 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.
