TTL Voltage Production

[ravindra123]

I am doing a project on synchronisation of camera and sensors. For triggering the camera i need 3.1 V TTL single ended signal. I am using PCI6024E. How can i produce that?....the digital output of the DAQ card is TTL...bt how can i adjust it to the high level of 3.1 V.

The DOs of the PCI-6024E are not able to generate this level. Therefore you will need some external hardware. What are the limits for the low and high levels of the trigger input of the camera ?

[ravindra123]

low level is zero and high voltage is 3.1 volta

[JB]

Yes but what are the limits for these levels ?

          Min [V]   Max [V]

Low    ?            ?

High   ?            ?

Will the input of the camera be damaged with 5V ? 3.1V may be the minimum for the high level.

There are voltage change over buffers out there.  The ones I've used are the 74LVCC4245.  Just do a search on Digikey.  You will need to supply a 5V and a 3.3V for it to change the levels.

hi.. I am using DAQ 6216. I want to generate a TTL pulse with 1ms on time and 10ms off time
