GENERAL DESCRIPTION FEATURES
Microelectronics Corp.
SM6B595
8-BIT LED DRIVER
The SM6B595 is specifically designed for
USE in LED DISPLAY.
This device contains an 8-bit shift register,
8 bit D-type storage register an d open-drain
NMOS output drivers.
The serial output allows for cascading of the
data from the shift register to additional
devices.
PIN ASSIGNMENTS
* Maximum output terminal voltage: 30V.
* Maximum continuous drain current:100mA.
* Typical R
DS(ON) :
5 Ω
* Devices are cascadable
* Low power consumption
* Serial data transfer rate: 25 MHz.
