MSC7171

12-Bit Grid Driver

This version: NMovS. C19791771

Previous version: Jul. 1996

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

• Driver output current

IOH: –50 mA (Only one driver output is in the high state)

IOL: 100 mA

• 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)
