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: 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.
