I would like to use the TI SN74LVC126A and SN74LVC244APW as a level converter for an 25MHz oscillator clock signal (from 3V3 logic to 1V8 logic). Therefore I would like to know the maximum rise/fall time (or slew rates) of the driver in this buffer. Also we would like to know the contribution of jitter by this device to the clock.
This part can be used as a tranlastor and should work fine at 25Mhz depending on the load. The output slew rates will also depend on the load. With a cmos load 5 to 10Pf the slew should be about 4ns for a single switch. jitter should be less than 20ps typ.
