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) Function Table Inputs CLR CLK D Output Q L X X L H ↑ H H H ↑ L L H ↓ X Q0 Note: H: High level L: Low level X: Immaterial ↑: Low to high transition ↓: High to low transition Q0: Output level before the indicated steady state input conditions were established.

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. 3 HD74LV273A Recommended Operating Conditions Item Symbol Min Max Unit Supply voltage range VCC 2.0 5.5 V Input voltage range VI 0 5.5 V Output voltage range VO 0 VCC V H or L Output current I OH — –50 µA VCC = 2.0 V — –2 mA VCC = 2.3 to 2.7 V — –6 VCC = 3.0 to 3.6 V — –12 VCC = 4.5 to 5.5 V — 50 µA VCC = 2.0 V — 2 mA VCC = 2.3 to 2.7 V — 6 VCC = 3.0 to 3.6 V — 12 VCC = 4.5 to 5.5 V 0 200 0 100 VCC = 3.0 to 3.6 V 0 20 VCC = 4.5 to 5.5 V –40 85 I OL ∆t /∆v Input transition rise or fall rate Operating free-air temperature Ta ns/V °C Note: Unused or floating inputs must be held high or low.
