Is there a universal level shifter for voltage translation?
New signal standards are constantly emerging, and voltage levels are perpetually dropping. Today’s design engineers regularly find themselves looking for solutions to solve communication issues among these mixed applications as many products are bidirectional and scalable from 1-bit to +32-bits with support for communicating power from 1.5V to 5V.
What’s the best way to do voltage translation?
The general way to handle voltage translation for such applications is to use high speed logic, and a combination of the WR/RD and CS pulses to set the direction of a more traditional level translating buffer like the SN74LVC1T45 and it’s 2, 8, 16 bit variants.
How to translate 5V signals to 3.3V signals?
To translate 5V signals to 3.3V signals, the simplest way is to make a voltage divider. A voltage divider consisting of a 1k and 2k resistor can perform this task. The output voltage of a voltage divider can be calculated by the following equation: Rx will be the resistor across which we measure output.
What kind of voltage translator does Pericom use?
Pericom offers great chip-to-chip interface between different I/O voltages ranging from 1.5/1.8/2.5/3.3 V to 5 V, and 0.8 V to 2.5 V. These translators are scalable from 16-bit to 32-bits and beyond. See following page for product listing.
Which is the universal level shifter ( ULS ) IC?
Diodes offers a variety of universal level shifter (ULS) ICs, translation ICs that provide mixed signal (TTL, HSTL and SSTL) as well as multiple supply voltages (5V, 3.3V, 2.5V, 1.8V and 1.2V).
How to convert voltage from one specifc range to another?
You could use a dual RRO op-amp (eg. AD8676) and ICL7660 as follows (single 5V supply) This has 0~5V output for -10~10V in. If you have to handle the -10V and +10V cases with an ADC that has a nominal 5V reference, then you may wish to increase R1 slightly to cover saturation voltage of the op-amps, resistor tolerances and so on, perhaps 5-10%.
What should the nominal voltage be for AVC +?
AVC+ can operate from 1.65V to 3.6V with a 2.5V nominal operating voltage. The wide operating voltage range makes AVC+ suitable for 1.8V, 2.5V or 3.3V operation. Can I apply any voltage in the nominal range (1.8V-2.5V for PI74AVC164245, and 1.5V-2.5V for PI74AVC164245LA) to the VCCA pin? For example, can I apply 2.0V to VCCA?
