Product details

Description

The HD74ALVCH16821 can be used as two 10-bit flip flops or one 20-bit flip flop.

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 ±24 mA (@V CC = 3.0 V).
Bus hold on data inputs eliminates the need for external pullup / pulldown resistors HD74ALVCH16821 Function Table Inputs OE L L L H CLK ↑ ↑ H or L X D H L X X H L Q0.
