Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | B | input | BCD data input B, latched by the strobe input; input voltage range -0.5 V to VDD+0.5 V. |
| 2 | C | input | BCD data input C, latched by the strobe input; input voltage range -0.5 V to VDD+0.5 V. |
| 3 | LT | input | Lamp Test input (active low) used to test the display; input voltage range -0.5 V to VDD+0.5 V. |
| 4 | BL | input | Blanking input (active low) that shuts off or intensity-modulates the display; input voltage range -0.5 V to VDD+0.5 V. |
| 5 | LE/STROBE | input | Latch Enable or Strobe input that stores or strobes the BCD code; minimum strobe pulse width 400 ns at VDD = 5 V. |
| 6 | D | input | BCD data input D, latched by the strobe input; input voltage range -0.5 V to VDD+0.5 V. |
| 7 | A | input | BCD data input A, latched by the strobe input; input voltage range -0.5 V to VDD+0.5 V. |
| 8 | VSS | power_in | Ground (VSS) reference terminal; all voltages are referenced to it. |
| 9 | e | output | 7-segment output e, sourcing up to 25 mA; blanked for BCD input codes > 1001. |
| 10 | d | output | 7-segment output d, sourcing up to 25 mA; blanked for BCD input codes > 1001. |
| 11 | c | output | 7-segment output c, sourcing up to 25 mA; blanked for BCD input codes > 1001. |
| 12 | b | output | 7-segment output b, sourcing up to 25 mA; blanked for BCD input codes > 1001. |
| 13 | a | output | 7-segment output a, sourcing up to 25 mA; blanked for BCD input codes > 1001. |
| 14 | g | output | 7-segment output g, sourcing up to 25 mA; blanked for BCD input codes > 1001. |
| 15 | f | output | 7-segment output f, sourcing up to 25 mA; blanked for BCD input codes > 1001. |
| 16 | VDD | power_in | Positive supply; recommended 3 V to 18 V, absolute maximum -0.5 V to +20 V referenced to VSS. |
