HD74LV574A
Octal Edge-Triggered D-type Flip-Flops with 3-state Outputs
ADE-205-280 (Z)
1st Edition
April 1999
Description
The HD74LV574A has eight edge-triggered D-type flip-flops with three-state outputs in a 20-pin package.
Data at the D inputs meeting set up requirements, are transferred to the Q outputs on positive going
transitions of the clock input. When the clock input goes low, data at the D inputs will be retained at the
outputs until clock input returns high again. When a high logic level is applied to the output control input,
all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the
state of the storage elements. 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 ±8 mA (@VCC = 3.0 V to 3.6 V), ±16 mA (@VCC = 4.5 V to 5.5 V)

Notes: 1. Input waveform: PRR ≤ 1 MHz, Zo = 50 Ω, tr ≤ 3 ns, tf ≤ 3 ns
2. Waveform-A is for an output with internal conditions such that the output is low except when disabled
by the output control.
3. Waveform-B is for an output with internal conditions such that the output is high except when disabled
by the output control.
4. The output is measured one at a time with one transition per measurement.
