Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

Blanking Input. When high, the display is blanked regardless of the levels of the other inputs. When low,
a character is displayed as determined by the data in the latches. The blanking input may be pulsed for
intensity modulation.
Latch Data Input A. Data on this input is entered into the latch when the Latch Strobe Input is low. The
binary weight of this input is 1.
Latch Data Input B. Data on this input is entered into the latch when the Latch Strobe Input is low. The
binary weight of this input is 2.
Latch Data Input C. Data on this input is entered into the latch when the Latch Strobe Input is low. The
binary weight of this input is 4.
Latch Data Input D. Data on this input is entered into the latch when the Latch Strobe Input is low. The
binary weight of this input is 8.
Common Ground. This is the negative terminal for all logic and LED currents except for the decimal points.

Left Decimal Point Cathode. This LED is not connected to the logic chip. If a decimal point is used, an
external resistor or other current-limiting mechanism must be connected in series with it.
Logic Supply (V
There is no pin at this location.
Right Decimal Point Cathode. This LED is not connected to the logic chip. If a decimal point is used, an
external resistor or other current-limiting mechanism must be connected in series with it.
Latch Strobe Input. When low, the data in the latches follow the data on the latch data inputs. When high,
the data in the latches does not change. If the display is blanked and then restored while this input is high,
the previously displayed character will again be displayed.
