SM6B595

㆔㈲ 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.
