Additional preview pages of the HD74LVC74 datasheet.

The HD74LVC74 has independent data, preset, clear, and clock inputs Q and Q outputs in a 14 pin package.

The logic level present at the data input is transferred to the output during the positive going transition of the clock pulse.

VCC = 2.0 V to 5.5 V All inputs VIH (Max. ) = 5.5 V (@VCC = 0 V to 5.5 V) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C) High output current ±24 mA (@VCC = 3.0 V to 5.5 V) HD74LVC74 Function Table Inputs PR L H L H H H H H H: L: X: ↓: ↑: Q0: Note: CLR H L L H H H H H CK X X X ↑ ↑ L H ↓ D X X X H L X X X Outputs Q H L H H L Q0 Q0 Q0.
