DM74AS1032A Quadruple 2-Input OR Driver
DM74AS1032A
Quadruple 2-Input OR Driver
General Description
This device contains four independent 2-input drivers, each of which performs the logic OR function. Each driver has increased output drive capability to allow the driving of high capacitive loads.
Features
s Switching specifications at 50 pF
s Switching specifications guaranteed over full tempera-ture and V CC range s Advanced oxide-isolated, ion-implanted Schottky TTL process s Improved line receiving characteristics
Ordering Code:
Devices also available in T ape and Reel. Specify by appending the suffix letter “X” to the ordering code.

Absolute Maximum Ratings (Note 1)
Note 1: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.The “Recommended Operating Conditions” table will define the conditions for actual device operation.
