Hi,

Can anyone say the difference between Buffer IC and a level translator IC ?

 

Hi Aruna.
Welcome to AAC.
Via Google.
Unlike the microcontroller, the buffer has a higher tolerance for being loaded down and the buffer will more faithfully output the correct voltages with fast rise times. A level translator is similar to a buffer in that it replicates signals and is tolerant to being loaded down by other stuff.

 

Buffer gives you more current at the same logic voltage levels.
Voltage translator gives you different logic voltage Levels.

 

Welcome to AAC!

A buffer is designed to provide a higher fanout than typical devices in a particular logic family. They can also be used to drive non-logic loads like LEDs, etc.

A level translator is designed to interface logic operating at different voltages.

 

there are different buffers and different level translators . . . even such that share the same functionality --e.g.-- provide fanout or line driving capability or , say , CMOS to TTL translation capability

Hi

Generally, in the context of digital circuits....
A buffer maintains the same input and output voltage levels but supports a greater output current load (fan out).
A level translator can change the input voltage level to a different output voltage level.

 

i think the "Buffer" on it's own is quite a floating term . . . but it may be just me.

as . . . try searching the "inverters" versus the "non-inverting buffers"
