3 - STATIC ELECTRICAL CHARACTERISTICS
(Tamb within operational range, VDD=4.75V to 13.2V, VSS=0V, unless otherwise specified)
Note 1 Output matching is calculated as the percent variation from Imax+Imin/2
Note 2 With a fixed resistor on the brightness input some variation in brightness will occur from one device to another.
Note 3 Absolute maximum for each output should be limited to 40mA.
Note 4 the Vo voltage should be regulated by the user.
4 - FUNCTIONAL DESCRIPTION
The M5481 uses the M5450 die which is packaged
to operate 2-digit alphanumeric displays with mini-
mal interface with the display and the data source.
Serial data transfer from the data source to the dis-
play driver is accomplished with 2 signals, serial
data and clock. using a format of a leading “1” fol-
lowed by the 35 data bits allows data transfer with-
out an additional load signal.
The 35 data bits are latched after the 36th bit is
complete, thus providing non-multiplexed, direct
drive to the display. Outputs change only if the se-
rial data bits differ from the previous time. Display
brightness is determined by control of the output
current for LED displays. A 1nF capacitor should
be connected to brightness control (pin 9) to pre-
vent possible oscillations.
A bloc diagram is shown on Figure 1. The output
current is typically 20 times greater than the cur-
rent into pin 9, which is set by an external variable
resistor.
The latter is an internal limiting resistor of 400
nominal value.
Figure 2 shows the input data format. A start bit of
logical “1” precedes the 35 bits of data. At the 36th
clock a LOAD is generated synchronously with the
high state of the clock, which loads the 35 bits of
the shift registers into the latches.
