Applications Information (Continued)

The BP_IN pin of the MM145453 can be used with an exter-

nally supplied signal, provided it has a duty cycle of 50%.

Any deviation from a precise 50% duty cycle will result in an

offset voltage on the LCD. The use of an external clock al-

lows synchronizing the display drive with AC power, other in-

ternal clocks, or DVM integration time to reduce interference

from the display. When using an external clock for the back

plane drive the internal oscillator should be disabled by con-

necting the OSC_IN pin directly to ground. This will prevent

possible internal oscillations, and reduce device dissipation.

The MM145453 is a pin out variation of the MM5453. For ad-

ditional applications information please refer to the MM5453

data sheet.
