Re: 5 V tolerant Io pads
thanks a lot
but can you tell me whether i can interface serial to parallel IC (operating at 5V)
directly with LPC2148 (working at 3.3V with 5 V tolerant IO pads) without damaging the microcontroller. please it will be a great help to me.
5 V tolerant Io pads
hi,
can any one tell me what 5V tolearant IO pads means. i am currently working on LPC2148 which works on 3.3V Vcc with its maximum Vcc being 3.6V. But the chip also has 5V volts tolerant IO pads. Does dat mean i can connect the IO pins with 5V without damaging the IC...
but the charging goes on to about a sec. i disconnect the circuit through a switch when the capacitors have charged to about 150V. but thy keep on charging for about a sec and the potential rises to 180V. and i want to keep the voltage constant at 150V but if i apply a high resistance in its...
i have 2 capacitors connected in parallel with the a flash tube.
they are charged by the a dc power supply and even if i disconnect the power supply with a switch the capacitors keep on charging... i cant seem to find the reason.
