Description
The HD74HCT74A 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. Preset and clear are independent of the clock and accomplished by a low level at the appropriate input.

Features
• VCC = 4.5 to 5.5 V operation
• Input terminal has protection diode
