A simple and convenient way to interface 2 relays for switching application in your project. This relay driver boosts the input impedance with a regular BC547 NPN transistor (or equivalent). Very ...

Many integrated circuits have undocumented features or abilities. This is one of them. The TLC555 output (pin 3) can sink a 100mA load to 1.28V. The open drain transistor reset (pin 7) can sink 100mA ...

BEVERLY, Mass.--(BUSINESS WIRE)-- IXYS Integrated Circuits Division (formerly Clare, Inc.), a wholly owned subsidiary of IXYS Corporation (NAS: IXYS) , announced the immediate availability of the ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

This chapter covers representative general-purpose relays used in the control circuits of most industrial, commercial, and consumer products. Relay names and terminology are in accordance with ...

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India, recently ...

Keithley Instruments has added to its 3700 system range of switch/multimeter and plug-in cards with the Model 3724 Dual 1X30 Solid State FET Relay Multiplexer Card and the Model 3750 Multifunction I/O ...
