Description
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. Preset and clear are independent of the clock and accomplished by a low level
at the appropriate input. Low voltage and high speed operation is suitable at the battery drive product (note
type personal computer) and low power consumption extends the life of a battery for long time operation.
Features
• V_CC = 2.0 V to 5.5 V
• All inputs V_IH (Max.) = 5.5 V (@V_CC = 0 V to 5.5 V)
• Typical V_OL ground bounce < 0.8 V (@V_CC = 3.3 V, Ta = 25°C)
• Typical V_OH undershoot > 2.0 V (@V_CC = 3.3 V, Ta = 25°C)
• High output current ±24 mA (@V_CC = 3.0 V to 5.5 V)
