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)
