OCTAL EDGE-TRIGGERED

D-TYPE FLIP-FLOPS

WITH 3-STATE OUTPUTS

DESCRIPTION

The U74LVC374 is an octal edge-triggered D-type flip-flop with

3-state outputs and 8 channels.

FEATURES

* Operate from 1.65V to 3.6V

* Max t_pdof 6.5ns at 3.3 V

* Typical V_OL< 0.8V @ V_CC=3.3V (Ta=25°C)

* Typical V_OH> 2.0V @ V_CC=3.3V (Ta=25°C)

* Power off disables outputs, permitting live insertion

* Halogen Free
