556 Timer Circuit design

Completed Posted 3 years ago Paid on delivery
Completed Paid on delivery

Provide a schematic design for a 556 dual timer IC base circuit to be triggered by a phototransistor with the result that two simultaneous 5v pulses are generated. The first pulse shall be approximately 50ms in duration and the second shall be approximately 1000ms in duration. The two timer circuits within the 556 IC shall be effectively interlocked such that the first 50ms pulse may not be repeated during the 1000ms pulse regardless of any intervening trigger event. The supply voltage for the system shall be 5v. If practicable, the design shall include the following components: Texas Instruments model TLC556CDR IC OSC TIMER DUAL 2.1MHZ 14-SOIC, datasheet available at:[login to view URL]; OR the Texas Instruments model TLC556IDR IC OSC TIMER DUAL 2.1MHZ 14-SOIC, same data sheet as above. The design shall also be based upon the model SFH 3310 570nm Phototransistor by OSRAM Opto Semiconductors Inc., datasheet available at: [login to view URL]

This is one small part of a larger product design and there is the potential for ongoing work if we find someone who is the rght fit

We need someone with significant real world experience with the 555/556
