Delayed timing mode (see Figure 12)*. With C0 = C1 = 00, bit D3 set PCM delayed or non-  
delayed timing. With C0, C1 = 01, 10, 11, bit D3 is ignored.

Nondelayed timing mode (see Figure 13)*. With C0 = C1 = 00, bit D3 set PCM delayed or  
nondelayed timing. With C0, C1 = 01, 10, 11, bit D3 is ignored.

T7507 driver output RD3c at logic low. If T7507 driver output RD3c is applied to the L8567  
SLIC RD3I input, this will place the relay driver output on the L8567, RD3O, into the relay  
not active state. If T7507 output RD3c is used to drive the logic inputs of an L7583 solid-  
state switch, a logic 0 is applied.

T7507 driver output RD3c at logic high. If T7507 driver output RD3c is applied to the L8567  
SLIC RD3I input, this will place the relay driver output on the L8567, RD3O, into the relay  
active state. If T7507 output RD3c is used to drive the logic inputs of an L7583 solid-state  
switch, a logic 1 is applied.  
T7507 driver output RD2c at logic low. If T7507 driver output RD2c is applied to the L8567  
SLIC RD3I input, this will place the relay driver output on the L8567, RD2O, into the relay  
not active state. If T7507 output RD2c is used to drive the logic inputs of an L7583 solid-  
state switch, a logic 0 is applied.

T7507 driver output RD1c at logic low. If T7507 driver output RD1c is applied to the L8567  
SLIC RD3I input, this will place the relay driver output on the L8567, RD1O, into the relay  
not active state. If T7507 output RD1c is used to drive the logic inputs of an L7583 solid-  
state switch, a logic 0 is applied.

* Delayed or nondelayed timing is a global parameter. All channels will use the most recently programmed value.  
Note: Upon powerup, D3 = D2 = D1 = D0 = 0; that is, delayed timing mode and all relay drivers in the not active state, or 0, 0, 0, are applied to  
L7583 solid-state relay, which is the idle/talk state.

* Receive gain of –3.5 and –7.0 will be achieved in a 200 + 680 || 0.1 µF termination, when using the T7507 with the L8567 SLIC, L7583  
switch, and 50 protection resistors.
