DM5401 - Quad 2-Input NAND Gates with Open-Collector Outputs

General Description

This device contains four independent gates each of which performs the logic NAND function The open-collector outputs require external pull-up resistors for proper logical operation Pull-Up Resistor Equations RMAX e VCC (Min) b VOH N1 (IOH) a N2 (IIH) VCC (Max) b VOL RMIN e IOL b N3 (IIL) Where N1 (IOH) e total maximum output high current for all outputs tied to pull-up resistor N2 (IIH) e total maximum input high current for all inputs tied to pull-up resistor N3 (IIL) e total maximum input low current for all inputs tied to pull-up resistor Connection Diagram Dual-In-Line Package TL F 6614 – 1 Order Number DM5401J DM5401W or DM7401N See NS Package Number J14A N14A or W14B Function Table Y e AB Inputs A L L H H B L H L H Output Y H H H L H e High Logic Level L e Low Logic Level C1995 National Semiconductor Corporation TL F 6614 RRD-B30M105 Printed in U S A Absolute Maximum Ratings (Note) If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Supply Voltage 7V Input Voltage 5 5V Output Voltage 7V Operating Free Air Temperature Range b 55 C to a 125 C DM54 DM74 0 C to a 70 C Storage Temperature Range b 65 C to a 150 C Note 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’’ table are not guaranteed at the absolute maximum ratings The ‘‘Recommended Operating Conditions’’ table will define the conditions for actual device operation Recommended Operating Conditions Symbol VCC VIH VIL VOH IOL TA Parameter Min Supply Voltage High Level Input Voltage Low Level Input Voltage High Level Output Voltage Low Level Output Current Fre
