L7583A/B/C/D Line Card Access Switch
Application (continued)
Table 17. Truth Table for L7583C/D
1. If TSD = 5 V, the thermal shutdown mechanism is disabled. If TSD is floating, the thermal shutdown mechanism is active.
2. Forcing TSD to ground overrides the logic input pins and forces an all OFF state.
3. Idle/Talk state.
4. TESTout state.
5. TESTin state.
6. Power ringing state.
7. Ringing generator test state.
8. Simultaneous TESTout and TESTin state.
9. All OFF state.
10. Simultaneous TESTout—Ring Test state.
A parallel in/parallel out data latch is integrated into the L7583C/D. Operation of the data latch is controlled by the logic level
input pin LATCH. The data input to the latch is the INPUT pin of the L7583C/D and the output of the data latch is an internal
node used for state control.
When the LATCH control pin is at logic 0, the data latch is transparent and data control signals flow directly from INPUT,
through the data latch to state control. Any changes in INPUT will be reflected in the state of the switches.
When the LATCH control pin is at logic 1, the data latch is active; the L7583C/D will no longer react to changes at the INPUT
control pin. The state of the switches is now latched; that is, the state of the switches will remain as they were when the
LATCH input transitioned from logic 0 to logic 1. The switches will not respond to changes in INPUT as long as LATCH is
held high.
Note that the TSD input is not tied to the data latch. TSD is not affected by the LATCH input. TSD input will override state con-
trol via INPUT and LATCH.
