HD74LV74A
Dual D–type Flip Flops with Preset and Clear
ADE-205-244 (Z)
1st Edition
March 1999
Description
The HD74LV74A has independent data, preset, clear, and clock inputs Q and
Q
outputs in a 14 pin
package. The input data is transferred to the output at the rising edge of clock pulse CLK. 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.
