DIGITAL CIRCUIT POWER SUPPLIES


Digital circuits are in hard -to- find and locate intermittent problems are traceable these kind of device to the power supply. Digital chips, because of their nature, the Power supply and filtering system will be very sensitive to any slight faults. Old TTL- type digital IC do not give any devices that much trouble, the supply voltage should be Between 4.75 and 5.25 volts.



























CMOS devices are more popular now but in a wider range and more voltage tolerance, noise, ripple effect is more and power supply glitches. Power line voltage spikes and glitches can be erratic And solid state equipment operation may damage the chip. It's a good cause plug in a more expensive electronic uninterpretable power supply ( UPS ) to use this Equipment .
