HD74LV273A
Octal D-type Flip-Flops with Clear
ADE-205-273 (Z)
1st Edition
April 1999
Description
The HD74LV273A has eight edge trigger D-type flip-flops with clear in a 20-pin package. Data on the D
input having the specified setup and hold times is transferred to the Q output on the low to high transition
of the clock input. The clear input when low, sets all outputs to a low state. Low-voltage and high-speed
operation is suitable for 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), ±16 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.
