PACDN010

The PACDN010 is designed as one kind of P/Active schottky diode memory bus terminators. Reflections of PACDN010 on high speed memory buses lead to undershoot and overshoot disturbances which may result in improper system operation. Resistor terminations PACDN010, when used to terminate high speed memory or data lines, increase power consumption and degrade output (high) levels resulting in reduced noise immunity. Schottky diode termination is the best overall solution for applications in which power consumption and noise immunity are critical considerations.

PACDN010 has five features. (1)Provides proper bus termination independent of card loading conditions. (2)Schottky diode technology; fast turn on and reverse recovery characteristics. (3)36 integrated diodes in a single package offers 18 channel, dual rail clamping action. (4)24-pin QSOP package saves board space and eases layout in space critical bus termination applications. (5)Available in 24-pin TSSOP package for component height constrained modules. Those are all the main features.

Some important standard specifications of PACDN010 have been concluded into several points as follow. (1)Its supply voltage would be from -0.3V to 7V. (2)Its channel clamp current continuous would be +/-50mA. (3)Its operating temperature range would be from 0°C to 70°C. (4)Its storage temperature range would be from -60°C to 150°C. (5)Its package power rating would be max 1.00W. And so on.

Also some diode characteristics of PACDN010 are concluded as follow. (1)Its diode forward voltage would be typ 0.65V and max 0.85V at If=16mA and would be typ 0.8V and max 1.0V at If=50mA. (2)Its max bus speed would be typ 125MHz. (3)Its channel leakage current would be typ 0.1uA and max 5uA. (4)Its input capacitance would be typ 5pF. (5)Its ESD protection would be min 2KV. And so on. At present we have not got so much information about this IC and we would try hard to get more information about it.
