GENERAL DESCRIPTION
The MSC7171 is a driver IC designed to directly drive the grids of fluorescent display tube. It contains a 12-bit shift register and 12 output drivers.
Display data is serially written into the internal 12-bit shift register on the rising edge of each clock pulse.
By setting the DUTY pin to "L", all driver outputs go "L". Blanking can be set using this function.
By setting the STANDBY pin to "H", all driver outputs go "L" and the MSC7171 enters the low current mode.

FEATURES
• Logic supply voltage : 5 V
• Driver supply voltage : 65 V

    IOH: –50 mA (Only one driver output is in the high state)
    IOL: 100 μA
• Directly connectable to VF display tube: no pull-down resistor required
• Data transfer cycle : 5 MHz
• Brightness control through DUTY pin
• Low-current mode can be set with STANDBY pin
• Package:
    24-pin plastic SOP (SOP24-P-430-1.27-K)(Product name: MSC7171GS-K)
