HD74ALVCH162721 outputs equivalent, 3.3-v 20-bit flip flops with 3-state outputs.
* 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 out.
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 ) in.
