DataSheet.in 9601 DM9601 Retriggerable One Shot June 1989 9601 DM9601 Retriggerable One Shot General Description These retriggerable one shots provide the designer with four inputs two active high and two active low This permits a choice of either leading-edge or trailing-edge triggering independent of input transition times When input conditons for triggering are met a new cycle starts and the external capacitor is rapidly discharged and then allowed to charge again The retriggerable feature allows for output pulse widths to be expanded In fact a continuous true output can be maintained by having an input cycle time which is shorter than the output cycle time Retriggering may be inhibited by tying the Q output to an active low input Features Y Y Y Y Y Y Y Y High speed operation input repetition rate l 10 MHz Flexibility of operation optional retriggering lock-out capability Output pulse width range 50 ns to % Leading or trailing edge triggering Complementary outputs inputs Input clamping diodes DTL TTL compatible logic levels Alternate Military Aerospace device (9601) is available Contact a National Semiconductor Sales Office Distributor for specifications Connection Diagram Dual-In-Line Package TL F 6610 – 1 Order Number 9601DMQB 9601FMQB DM9601J DM9601W or DM9601N See NS Package Number J14A N14A or W14B Function Table Inputs A1 H X X L L L X X X H A2 H X X X X X L L L B1 X L X H B2 X X L H H Outputs Q L L L L Q H H H H H e L e Xe High Logic Level Low Logic Level Either Low or High Logic Level Transition High to Low Level Transition u H H u e Low to High Level u H H L H ve u H H H H e Positive Pulse e Negative Pulse u H H H v v v v H C1995 National Semiconductor Corporation TL F 6610 RRD-B30M105 Printed in U S A DataSheet.in 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 Operating Free Air Temperature Range b 55 C to a 125 C Military Commercial 0 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 Parameter Min Supply Voltage High Level Input Voltage TA e b55 C TA e 0 C TA e 25 C TA e 75 C TA e 125 C VIL Low Level Input Voltage TA e b55 C TA e 0 C TA e 25 C TA e 75 C TA e 125 C IOH IOL TA High Level Output Current Low Level Output Current Free Air Operating Temperature b 55 Military Nom 5 Max 55 Min 4 75 Commercial Nom 5 Max 5 25 Units V 45 2 19 17 18 16 15 0 85 0 85 09 0 85 0 85 0 85 b 0 72 b 0 96 V V mA mA C 10 125 0 12 8 75 Electrical Characteristics over recommended operating free air temperature range (unless otherwise noted) Symbol VI VOH VOL Parameter Input Clamp Voltage High Level Output Voltage Low Level Output Voltage Conditions (Note 3) VCC e Min II e b12 mA VCC e Min IOH e Max VIL e Max VIH e Min (Note 4) VCC e Min VIL e Max (Note 4) IOL e Max VIH e Min MIL COM 24 04 0 45 60 MIL VIN e 0 40V COM VIN e 0 45V VCC e Max (Notes 2 and 4) VCC e Max MIL COM b 10 b 10 b1 6 b1 6 b 40 b 40 Min Typ (Note 1) Max b1 5 Units V V V IIH IIL IOS ICC High Level Input Current Low Level Input Current Short Circuit Output Current Supply Current VCC e Max VI e 4 5V VCC e Max mA mA mA mA 25 Note 1 All typicals are at VCC e 5V TA e 25 C Note 2 Not more than one output should be shorted at a time Note 3 Unless otherwise noted RX e 10k between PIN 13 and VCC on all tests Note 4 Ground PIN 11 for VOL test on PIN 6 VOH and IOS tests on PIN 8 Open PIN 11 for VO... |
