DM64ALS08/DM74ALS08 Quad 2-Input AND Gate Y General Description This device contains four independent gates, each of which performs the logic AND function. The DM64ALS08 version features the same performance as the standard version DM74ALS08 with a guarantee over an extended temperature range (b40§ C to a 85§ C). Y Y Y Features Y Y Advanced oxide-isolated, ion-implanted Schottky TTL process Functionally and pin for pin compatible with Schottky and low power Schottky TTL counterpart Improved AC performance over Schottky and low power Schottky counterparts DM64ALS08 guaranteed over extended temperature b 40§ C to a 85§ C Switching specifications at 50 pF Switching specifications guaranteed over full temperature and VCC range Connection Diagram Dual-In-Line Package TL/F/6271 – 1 Order Number DM64ALS08M, DM64ALS08N, DM74ALS08M, DM74ALS08N or DM74ALS08SJ See NS Package Number M14A, M14D or N14A Function Table Y e AB Inputs Output A B Y L L H H L H L H L L L H H e High Logic Level L e Low Logic Level C1995 National Semiconductor Corporation TL/F/6271 RRD-B30M115/Printed in U.
