- BCD To seven-segment decoder.
-
- Use this component to drive a seven-segment display.
- When the Latch Enable input (_LE) is LOW, the state
- of the segment outputs is determinated by the data
- on the BCD inputs (A, B, C, D).
- When the Latch Enable input goes high, the last
- data present in the BCD inputs is stored in the
- latches and the Segment Outputs remain stable.
-
- When the Lamp Test input (_LT) is LOW, all the
- segment outputs are HIGH independent of all other
- input conditions. With the Lamp Test input HIGH
- a LOW on the Blanking input (_BI) forces all the
- segment outputs LOW.
- The Lamp Test input and the Blanking input do not
- affect the latch circuit.
-
- You can drag this component to another position
- by clicking inside the body of the port, hold
- the mouse button, move to the new position,
- and release the mouse button.
