  1. 1. DM7408 Quad 2-Input AND Gates August 1986 Revised July 2001 DM7408 Quad 2-Input AND Gates General Description This device contains four independent gates each of which performs the logic AND function. Ordering Code: Order Number Package Number Package DescriptionDM7408N N14A 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Connection Diagram Function Table Y = AB Inputs Output A B Y L L L L H L H L L H H H H = HIGH Logic Level L = LOW Logic Level© 2001 Fairchild Semiconductor Corporation DS006498 www.fairchildsemi.com
  2. 2. DM7408 Absolute Maximum Ratings(Note 1) Note 1: The “Absolute Maximum Ratings” are those values beyond which Supply Voltage 7V the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Input Voltage 5.5V Characteristics tables are not guaranteed at the absolute maximum ratings. Operating Free Air Temperature Range 0°C to +70°C The “Recommended Operating Conditions” table will define the conditions for actual device operation. Storage Temperature Range −65°C to +150°C Recommended Operating Conditions Symbol Parameter Min Nom Max Units VCC Supply Voltage 4.75 5 5.25 V VIH HIGH Level Input Voltage 2 V VIL LOW Level Input Voltage 0.8 V IOH HIGH Level Output Current −0.8 mA IOL LOW Level Output Current 16 mA TA Free Air Operating Temperature 0 70 °C Electrical Characteristics over recommended operating free air temperature range (unless otherwise noted) Typ Symbol Parameter Conditions Min Max Units (Note 2) VI Input Clamp Voltage VCC = Min, II = −12 mA −1.5 V VOH HIGH Level VCC = Min, IOH = Max 2.4 3.4 V Output Voltage VIL = Max VOL LOW Level VCC = Min, IOL = Max 0.2 0.4 V Output Voltage VIH = Min II Input Current @ Max Input Voltage VCC = Max, VI = 5.5V 1 mA IIH HIGH Level Input Current VCC = Max, VI = 2.4V 40 µA IIL LOW Level Input Current VCC = Max, VI = 0.4V −1.6 mA IOS Short Circuit Output Current VCC = Max (Note 3) −18 −55 mA ICCH Supply Current with Outputs HIGH VCC = Max 11 21 mA ICCL Supply Current with Outputs LOW VCC = Max 20 33 mA Note 2: All typicals are at VCC = 5V, TA = 25°C. Note 3: Not more than one output should be shorted at a time.
