How to shift 3.3 voltage level to 5V most efficiently?

hello

wanna shift a 3.3 voltage level(digital logic ) to a 5v logic whats the best and efficient process.

Re: voltage shifter

YOUR QUESTION IS OPEN ENDED BECOUSE
YOU FAILED TO SPECIFY WHAT YOUR SHIFTING

A BUS?? A SINGLE RAIL

BE MORE SPECIFIC PLEASE

THERE ARE DEDICATED BUFFERS FOR LOGIC ARRAYS
AND ALSO IC'S {CHARGE PUMPS} TO DO THIS JOB FOR RAILS

voltage shifter

a bus

Re: voltage shifter

how many...8? ,16?
there are buffer for each of this...
you can use 8 pcs single buffer.
or one pc octal buffer.

voltage shifter

a bus of 11 or 8+3

MC74HC245A - Octal 3-states non-inverting Bus Tranceiver
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.

Supply Voltage (Referenced to GND) min 2.0 Volt max 6.0 Volt

Operate this chip with 3.8 Volt DC supply, at this condition VOH (High Level Output Voltage) and VOL (Low Level Output Voltage) still meet 5 Volt logic device VIH (High Level Input Voltage) and VIL (Low Level Input Voltage) requirement

Yes, The 74 series chips.

so perhaps a display ....

Please look at this solution implemented with MOSFETs:

Re: voltage shifter

Texas Instruments makes tons of level shifters. They have a handy online selsction tool. Check it out
