Logic level converter IC

[jerryvdk]

Hi,

Does any one knows an ic/circuit that can convert a dc level(10-30V dc ) to TTL level?

If the 10-30V will always be driving the TTL input, use a resistor voltage divider into an op-amp comparator.

Well, in case of TTL output i.e. 5V, you can also use a voltage Regulator IC which is LM7805 .. It gives constant 5V at output and input range is also upto 25V to 30V .. Read datasheet of lm7805 as well ..

Hi,

it depends on switching thresholds.

Specify:
* the max. input voltage to get LOW output
* the min. input voltage to get HIGH output

Please specify purpose like switching speed, direction, current source and sink capabilities, etc.
Analog Devices have a very good range of isolators.
