HD74ALVCH162721 Overview
The HD74ALVCH162721’s twenty flip flops are edge triggered D-type flip flops with qualified clock storage. On the positive transition of the clock (CLK) input, the device provides true data at the Q outputs, provided that the clock enable (CLKEN ) input is low. If CLKEN is high, no data is stored.
HD74ALVCH162721 Key Features
- VCC = 2.3 V to 3.6 V
- Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)
- Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C)
- High output current ±12 mA (@V CC = 3.0 V)
- Bus hold on data inputs eliminates the need for external pullup / pulldown resistors
- All outputs have equivalent 26 Ω series resistors, so no external resistors are required
