Description
Device address input pins. The binary code set up on
these pins, must match the address field of the control
word, before device access may be achieved. These
Schmitt-triggered inputs have on-chip pull-up resistors.
This output is used for the manufacturers test requirements
and MUST be left open.
Constant Current Drain Select.This Schmitt-triggered
input has on-chip pullup provided.
High current LED drive terminal outputs.
to the LED's. A resistor is connected from this pin to V
Active low input that enables the internal LED status word
to be output from the DOUT pin. This Schmitt-triggered
input has on-chip pullup provided.
Internally Unconnected.
External clock Schmitt-triggered input runs at 8X the data
rate (Baud rate).
This active low Schmitt-Trigger input may be used to
reset all internal registers. When active (low) this input
will cause all LED's to be driven for the duration of MRST
(lamp test). When MRST goes inactive all LED's will be
turned off. On-chip pullup provided.
0V Supply Input for logic (0V)
Serial data input. Accept data in the form of an 11-bit
information word. This Schmitt-triggered input has on-
chip pullup provided.
Negative Supply Inputs (-5V)
Positive Supply Inputs (+5V)
