SM6B595F

㆔合微科股份㈲限公司 SAMHOP Microelectronics Corp. SM6B595 8-BIT LED DRIVER GENERAL DESCRIPTION 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. FEATURES * 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.

SM6B595 8-BIT LED DRIVER PIN DESCRIPTION Pin NO. 1 2 3 4-7 8 Pin Name NC Vcc SER IN OUT0~3 SRCLR No connection 5V supply voltage terminal. Input terminal of a serial-data for shift-register. Output terminals. Input terminal of clear signal for shift-register. When SRCLR is low, the input shift-register is cleared. Input terminal of output enable. All outputs (OUT0~7) do off with "H" level of G-terminal, and do on with "L" level input. Ground terminal. Input terminal of a clock for storage-register. Data transfer through storage-register on the rising edge of the storageregister clock. Input terminal of a clock for shift-register. Data transfer through shift-register on the rising edge of the shift-register clock. Output terminals. Output terminal of serial-data for next SER IN terminal. Ground terminal. No connection.
