PDN003

CALIFORNIA MICRO DEVICES PDN003 Octal Schottky Diode Network Features • Highly effective termination on controlled and uncontrolled line impedances • 8 terminating lines/package Applications • Reduce undershoots and multiple triggering on high speed data lines • ESD protection Refer to AP-201 Termination Application Note for further information. Product Description Undershoot disturbances on high speed data lines cause multiple triggering and can result in improper system operation. Resistors used for terminating these data lines increase power consumption and can degrade output high levels resulting in reduced noise immunity. Schottky diodes are recommended for termination. CAMD’s PDN003 Integrated Clamp Diode Network minimizes the undershoots and provides effective termination on high speed data lines SCHEMATIC CONFIGURATION CH1 CH2 CH3 CH4 CH5 CH6 CH7 CH8 1 2 3 4 5 6 7 8 Pins 9 and 16 not connected GND GND GND GND GND GND 15 13 12 11 10 14 S TA N D A R D PA R T O R D E R I N G I N F O R M AT I O N Package Pins 16 Style Narrow SOIC Tubes PDN003/T Ordering Part Number Tape & Reel PDN003/R Part Marking PDN003 S TA N D A R D S P E C I F I C AT I O N S Diode Forward Voltage @ IF = 16mA @ IF = 50mA Su p p l y Vo l t a g e, VP− VN Operating Temperature Range Channel Clamp Current (duration ≤ 100µs, duty cycle ≤ 20%) Channel Leakage, 0 VIN ≤ VDD Input Capacitance @ VIN = 0V, f = 1MHz @ VIN = 2V Power Dissipation, IF ≤ 10mA/Channel, TA = 25°C Storage Temperature Package Power Rating © 2000 California Micro Devices Corp.
