DESCRIPTION
The 74LVX257 is a low voltage CMOS QUAD 2 CHANNEL MULTIPLEXER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power, battery operated and low noise 3.3V applications.

■ HIGH SPEED: tPD=5.8ns (TYP.) at VCC = 3.3V
■ 5V TOLERANT INPUTS
■ POWER-DOWN PROTECTION ON INPUTS
■ INPUT VOLTAGE LEVEL: VIL = 0.8V, VIH = 2V at VCC =3V
■ LOW POWER DISSIPATION: ICC = 4 µA (MAX.) at TA=25°C
■ LOW NOISE: VOLP = 0.3V (TYP.) at VCC =3.3V
■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4 mA (MIN) at VCC =3V
■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL
■ OPERATING VOLTAGE RANGE: VCC(OPR) = 2V to 3.6V (1.2V Data Retention)
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 257
■ IMPROVED LATCH-UP IMMUNITY
