Qualification Pedigree⁽¹⁾
ESD Protection Exceeds 2000 V Per MIL-STD-883, Method 3015; Exceeds 200 V Using Machine Model (C = 200 pF, R = 0)
Operates From 2 V to 3.6 V
Inputs Accept Voltages to 5.5 V
Max t_pd of 4.6 ns at 3.3 V
Typical V_OLP (Output Ground Bounce) <0.8 V at V_CC = 3.3 V, T_A = 25°C
Typical V_OHV (Output V_OH Undershoot) >2 V at V_CC = 3.3 V, T_A = 25°C

⁽¹⁾ Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range. This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold compound life. Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits.

DESCRIPTION/ORDERING INFORMATION

The SN74LVC257A-EP quadruple 2-line to 1-line data selector/multiplexer is designed for 2.7-V to 3.6-V V_CC operation.

The device is 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 this device as a translator in a mixed 3.3-V/5-V system environment.

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