Some outputs are via Dual Differential Line Driver type DS8830. This device will interface with standard TTL systems. The differential outputs are balanced and are designed to drive long lengths of coaxial cable, strip...
U1 CD4541 is a Timer with Long Duration Ability. This timer is started by a low pulse from earlier circuit, when the temperature goes above setpoint, a low state is at U2A inputs, this...
I am having trouble preventing my rs latch from erroneously setting. The circuit is a voltage threshold detection circuit with a nand gate whose output is tied to a SR latch.
I’m looking for a source of decade counters and wonder if you can help? I don’t want to build the counter, I want to buy a functioning counter module. Do you have source suggestions?...
CD4538 is a dual Monostable Multivibrator. When you trigger the chip the output sends off one single pulse or one high-low event. Mixed Circuits Analog with Digital The T+ pin 4 of U1a is...
I had to once interface an high voltage circuit to PC, The uC had to communicate thru RS232–Comm port–Serial Port. Part of the 80C31 8051 SBC Even though i had isolation at the sensors...
I have a question about your “Long Duration Timer” circuit, del20017 found here ..Long Duration Timer Clock You have labeled U1 as a 4093. A 4093 is a NAND with schmitt trigger inputs, yet...
