Notes: *1 Voltage for logic with respect to VSS
*2 Stresses beyond the "Absolute Maximum Ratings" may cause permanent damage to the device.
*3 Thermal resistance of the package (between junction and atmosphere) The junction temperature (Tj) expressed by the equation below must not exceed 150°C. Tj=P ¥ Rja + Ta (P: Maximum power consumption of IC)




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.
