Input and Output Function
A, B, C, and D (binary code) Input
A, B, C and D are binary-coded decimal inputs corresponding to 1, 2,
4 or 8.
Latch Input
When the Latch input is set to level L, the display at the time is
maintained. (DP and BI inputs are independent.)
DP (Decimal Point)
When the DP input is set to level L, the decimal point turns on.
BI (Zero Blanking Input)
When the BI input is set to level H with 0 displayed, the display is
blanked.
BO (Blanking Output)
The BO output goes to level H during zero blanking. Leading zeros can
be suppressed by connecting the BO to the BI on the lower digits.
Note:
× indicates the display after inputting the Latch signal is maintained regardless of
the voltage level of H or L.
∆ indicates the display is not affected by voltage level of H or L.
DP (decimal point) turns on when the DP input signal is in level L.
