a HD74LV74A Dual D–type Flip Flops with Preset and Clear ADE-205-244 (Z) 1st Edition March 1999 Description The HD74LV74A has independent data, preset, clear, and clock inputs Q and Q outputs in a 14 pin package. The input data is transferred to the output at the rising edge of clock pulse CLK. Low-voltage and high-speed operation is suitable for the battery-powered products (e.g., notebook computers), and the low-power consumption extends the battery life. Features • • • • • • VCC = 2.0 V to 5.5 V operation All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VO (Max.) = 5.5 V (@VCC = 0 V) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°C) Output current ±6 mA (@VCC = 3.0 V to 3.6 V), ±12 mA (@VCC = 4.5 V to 5.5 V) Function Table Inputs Outputs PRE CLR CLK D Q Q L H X X H L H L X X L H L L X X H*1 H*1 H H ↑ H H L H H ↑ L L H H H ↓ X Q0 Q0 Note: H:High level L:Low level X:Immaterial ↑:Low to high transition ↓:High to low transition Q0:The level of Q immediately before the input conditions shown in the above table are determined. 1.:Q and Q will remain HIGH as long as Preset and Clear are Low, but Q and Q are unpredictable, if Preset and Clear go HIGH simultaneously.
