Features: 9602 DM9602 Dual Retriggerable Resettabl e One Shots June 1989 9602 DM9602 Dua l Retriggerable Resettable One Shots Ge neral Description These dual resettable retriggerable one shots have two input s per function one which is active high and one which is active low This allow s the designer to employ either leading -edge or trailing-edge triggering which is independent of input transition tim es When input conditions for triggering are met a new cycle starts and the ext ernal capacitor is allowed to rapidly d ischarge and then charge again The retr iggerable feature permits output pulse widths to be extended In fact a continu ous true output can be maintained by ha ving an input cycle time which is short er than the output cycle time The outpu t pulse may then be terminated at any t ime by applying a low logic level to th e RESET pin Retriggering may be inhibit ed by either connecting the Q output to an active high input or the Q output t o an active low input Features Y Y Y Y Y Y Y 70 ns to % outp.

Description:
The Microchip Technology Inc. 93LC76/86 are 8K and
16K low voltage serial Electrically Erasable PROMs.
The device memory is configured as x8 or x16 bits
depending on the ORG pin setup. Advanced CMOS
technology makes these devices ideal for low power
nonvolatile memory applications. These devices also
have a Program Enable (PE) pin to allow the user to
write-protect the entire contents of the memory array.
The 93LC76/86 is available in standard 8-pin PDIP and
8-pin surface mount SOIC packages.
