DESCRIPTION

The 74LVX238 is a low voltage CMOS 3 TO 8 LINE DECODER 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 = 5.5ns (TYP.) at VCC = 3.3V

■ 5V TOLERANT INPUTS

■ INPUT VOLTAGE LEVEL:VIL=0.8V, VIH=2V at VCC=3V

■ LOW POWER DISSIPATION:ICC = 2 µA (MAX.) at TA=25°C

■ LOW NOISE:VOLP = 0.3V (TYP.) at VCC = 3.3V

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN)

■ 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 138

■ IMPROVED LATCH-UP IMMUNITY

■ POWER DOWN PROTECTION ON INPUTS
