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.

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 150C.
