DESCRIPTION

The 74LVQ74 is a low voltage CMOS DUAL D-TYPE FLIP FLOP WITH PRESET AND CLEAR NON INVERTING 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.

■ HIGH SPEED: fMAX = 250 MHz (TYP.) at VCC = 3.3V

■ COMPATIBLE WITH TTL OUTPUTS

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

■ LOW NOISE: VOLP = 0.2 V (TYP.) at VCC = 3.3V

■ 75Ω TRANSMISSION LINE DRIVING CAPABILITY

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

■ PCI BUS LEVELS GUARANTEED AT 24 mA

■ 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 74

■ IMPROVED LATCH-UP IMMUNITY
