DESCRIPTION

The 74LVQ20 is a low voltage CMOS DUAL 4-INPUT NAND GATE fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and low noise 3.3V applications.

The internal circuit is composed of 3 stages including buffer output, which enables high noise immunity and stable output.

All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

■ HIGH SPEED: tPD = 5.3 ns (TYP.) at VCC = 3.3 V

■ COMPATIBLE WITH TTL OUTPUTS

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

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

■ 75? TRANSMISSION LINE DRIVING CAPABILITY

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 12mA (MIN) at VCC = 3.0 V

■ PCI BUS LEVELS GUARANTEED AT 24 mA

■ BALANCED PROPAGATION DELAYS: tPLH ? tPHL

■ OPERATING VOLTAGE RANGE: VCC(OPR) = 2V to 3.6V

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 20

■ IMPROVED LATCH-UP IMMUNITY
