9602 DM9602 Dual Retriggerable Resettable One Shots June 1989 9602 DM9602 Dual Retriggerable Resettable One Shots General Description These dual resettable retriggerable one shots have two inputs per function one which is active high and one which is active low This allows the designer to employ either leading-edge or trailing-edge triggering which is independent of input transition times When input conditions for triggering are met a new cycle starts and the external capacitor is allowed to rapidly discharge and then charge again The retriggerable feature permits output pulse widths to be extended In fact a continuous true output can be maintained by having an input cycle time which is shorter than the output cycle time The output pulse may then be terminated at any time by applying a low logic level to the RESET pin Retriggering may be inhibited by either connecting the Q output to an active high input or the Q output to an active low input Features Y Y Y Y Y Y Y 70 ns to % output width range Resettable and retriggerable 0% to 100% duty cycle TTL input gating leading or trailing edge triggering Complementary TTL outputs Optional retrigger lock-out capability Pulse width compensated for VCC and temperature variations Alternate Military Aerospace device (54xxx) is available Contact a National Semiconductor Sales Office Distributor for specifications Connection Diagram Dual-In-Line Package TL F 6611 – 1 Order Number 9602DMQB 9602FMQB or DM9602N See NS Package Number J1...
