HD74LVC74

Dual D-type Flip Flops with Preset and Clear

ADE-205-066C(Z)

Rev.3

September 1995

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

• 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)
