Hi = Alan,

 

The TC430CPA may be equivalent to = the TSC430, manufactured by Teledyne Components.  US Patent 5500615 = references this device:

 

“Another CCD driver is the TSC430, manufactured by = Teledyne Components of Mountain View, Calif. This driver has the input and output = power supplies decoupled, but uses complementary FETs so that during transition there = is a crossover current through both FETs. At high frequencies these FETs get = hot and use a considerable amount of power. Also the rise time at the output is = a function of the "ON" impedance of the = FETs”.

The Teledyne TSCXXX power driver = products were later recoded to TCXXX, but we can find no data sheets for the = TSC430 from Teledyne and have no record of a TC430 from = Telcom.

Hi;

I am looking for a data sheet for TC430CPA, originally made by Telecom =
Semiconductors which was bought out by Microchip in 1999 or 2000. =  There
are many TC4xx devices listed but not TC430CPA.  Is the datasheet available?

Thanks,
