Philips Semiconductors Product specification
Octal D-type flip-flop with reset; positive
edge-trigger; open drain outputs
74HCT7273
RECOMMENDED OPERATING CONDITIONS
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134); voltages are referenced to GND (ground = 0 V).
Note
1. For DIP package: above 70 °C the value of P
D
derates linearly with 12 mW/K.
2. For SO package: above 70 °C the value of P
D
derates linearly with 8 mW/K.
