HD74ALVCH162721 Datasheet (Hitachi Semiconductor) - 3.3-V 20-bit Flip Flops with 3-state Outputs

HD74ALVCH162721, 3.3-V 20-bit Flip Flops with 3-state Outputs

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 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 / pul
