DM7442A Datasheet | Fairchild Semiconductor

Description These BCD-to-decimal decoders consist of eight inverters and ten, four-input NAND gates. The inverters are connected in pairs to make BCD input data available for decoding by the NAND gates. Full decoding of input logic ensures that all outputs remain off for all invalid (10- 15) input conditions. Features s Diode clamped inputs s Also for application as 4-line-to-16-line decoders; 3-line-to-8-line decoders s All outputs are high for invalid input conditions s Typical power dissipation 140 m W s Typical propagation delay 17 ns Ordering Code: Order Number DM7442AN Package Number N16E Package Description 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Connection Diagram © 2000 Fairchild Semiconductor Corporation DS006516 .fairchildsemi.

Absolute Maximum Ratings(Note 1) Supply Voltage Input Voltage Operating Free Air Temperature Range Storage Temperature Range 7V 5.5V 0°C to +70°C - 65°C to +150°C 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 “Remended Operating Conditions” table will define the conditions for actual device operation. Remended Operating...
