NLSF595 Datasheet, PDF (1/16 Pages) ON Semiconductor – Serial (SPI) Tri-Color LED Driver

NLSF595
Serial (SPI) Tri−Color
LED Driver
The NLSF595 is advanced CMOS shift register with open drain
outputs fabricated with 0.6 mm silicon gate CMOS technology. This
device is used in conjunction with a microcontroller, with only one
dedicated line. All pins have Overvoltage Protection that allows
voltages above V_CC up to 7.0 V to be present on the pins without
damage or disruption of operation of the part, regardless of the
operating voltage. This device may be used between 2.0 and 5.5 volts,
the output driver level may be independent of supply voltage:
0−7.0 volts.
Features
• Parallel Outputs are Open Drain Capable of Sinking > 12 mA
Output Withstands up to +7.0 Regardless of V_CC
• Standard Serial (SPI) Interface, Data, Clock, Enable (Low)
• All Inputs CMOS Level Compatible
• Frees up I/O around a Microcontroller
• Only One Pin Dedicated to this Device (Latch Enable)
• Output Enable may be Permanently Pulled Low
• High Speed Clocking, Fmax > 25 MHz (Shift Clock)
• Eight Bits Parallel Output
• Double Buffered Outputs, so Register may Fill without Affecting
Output
• STD CMOS Serial Output, may be used to Cascade more than One
Device
• Each Part Controls Two Tri−Color LEDs
• Two Devices can Control 5 Tri−Color LEDs
• Low Leakage: I_CC = 2.0 mA (Max) at T_A = 25°C
• Latchup Performance Exceeds 100 mA
• QFN−16/TSSOP−16 Packages
• ESD Performance: Human Body Model; > 2000 V,
Machine Model; > 200 V
• Functionally Similar to the Popular 74VHC595
• Pb−Free Packages are Available
