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)

Notes: The absolute maximum ratings are values which must not individually be exceeded, and furthermore,

no two of which may be realized at the same time.

1. The input and output voltage ratings may be exceeded if the input and output clamp-current
ratings are observed.

2. This value is limited to 5.5 V maximum.

3. The maximum package power dissipation was calculated using a junction temperature of 150°C.
