概览

NLSF595 是一款先进的高速 CMOS 移位寄存器,带开漏输出,采用 0.6μm 硅门极 CMOS 工艺制造。该器件配合微控制器使用,仅使用一个专门线路。所有引脚均具有过电压保护,使得引脚上能够存在高于 VCC 最多 7.0 V 的电压,而不会损坏或中断零件的运行,而无论运行电压如何。该器件可在 2.0 到 5.5 V 之间使用,输出驱动器电平可独立于电源电压: 0-7.0 V。

  • Parallel Outputs are Open Drain Capable of Sinking > 12 mA Output Withstands up to +7.0 Regardless of VCC
  • 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: ICC = 2.0 µA (Max) at TA = 25°C
  • Latchup Performance Exceeds 100 mA
  • TSSOP-16 Package
  • ESD Performance: HBM > 1000 V; MM > 100 V
  • Functionally Similar to the Popular 74VHC595
