DM74ALS1008A
Quadruple 2-Input AND Buffer
General Description
These devices contain four independent 2-input buffers, each of which performs the logic AND function. The DM74ALS1008A is a buffer version of the DM74ALS08.
Features
■Switching specifications at 50 pF
■Switching specifications guaranteed over full temperature and VCC range
■Advanced oxide-isolated, ion-implanted Schottky TTL process
■Improved line receiving characteristics

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.
