| DM74AS34 Hex Non-Inverter September 1986 Revised March 2000 DM74AS34 Hex Non-Inverter General Description These devices contain six independent gates, each of which performs the logic identity function. Features s Switching specifications at 50 pF s Switching specifications guaranteed over full temperature and VCC range s Advanced oxide-isolated, ion-implanted Schottky TTL process Ordering Code: Order Number DM74AS34N Package Number N14A Package Description 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Connection Diagram Function Table Y=A Input A H L H = HIGH Logic Level L = LOW Logic Level Output Y H L (c) 2000 Fairchild Semiconductor Corporation DS006281 www.fairchildsemi.com DM74AS34 Absolute Maximum Ratings(Note 1) Supply Voltage Input Voltage Operating Free Air Temperature Range Storage Temperature Range Typical JA N Package 84.5C/W 7V 7V 0C to +70C -65C to +150C 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.
