ELECTRICAL CHARACTERISTICS

5.1

Power ON / OFF Sequence

There are no deleterious effects associated with power ON and OFF of this display; however, rapid ON/OFF
sequencing is not recommended. The power/data connector should not be connected/disconnected while
power is applied.
CAUTION: Do not apply data or strobe signals unless logic power is also applied; otherwise, the input
Because of the power-up cycle within the microprocessor, rise time of the power supply should be less than
100mS. The display module is not ready to accept data for 500mS.
5.2

Interface Signals

All logic signals abide by the following convention: logic "1" is a high, logic "0" is a low.
Input Levels:
Logic 1 > 2.4VDC @ 1µA.
Logic 0 < 0.5VDC @ 1.6mA.
Output Levels:
Logic 1 > 3.5VDC @ 150µA.
Logic 0 < 0.5VDC @ 4mA.
All parallel interface lines are internally pulled up using 10K resistors connected to the +5V supply.
