L7582 Tip Ring Access Switch
Application
12-2366.c (F)
Figure 7. Typical TRAS Application, Idle, or Talk State Shown
Table 13. Truth Table
1. If T
SD
= 5 V, the thermal shutdown mechanism is disabled. If T
SD
is floating, the thermal shutdown mechanism is active.
2. Forcing T
SD
to ground overrides the logic input pins and forces an all OFF state.
3. Idle/Talk state.
4. Power ringing state.
5. Test out or message waiting state.
6. All OFF state.

A parallel in/parallel out data latch is integrated into the
L7582. Operation of the data latch is controlled by the
logic level input pin LATCH. The data input to the latch
is the IN
RING
and IN
ACCESS
pins of the L7582, 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 IN
RING
and IN
ACCESS
, through the data latch to
state control. Any changes in IN
RING
and IN
ACCESS
will
be reflected in the state of the switches.
When the LATCH control pin is at logic 1, the data latch
is active—the L7582 will no longer react to changes at
the IN
RING
and IN
ACCESS
control pins. 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 IN
RING
and IN
ACCESS
as
long as LATCH is held high.
Note that the T
SD
input is not tied to the data latch. T
SD
is not affected by the LATCH input. T
SD
input will over-
ride state control via IN
RING
, IN
ACCESS
, and LATCH.
