Pin Name
MUTE
Internal Equivalent Circuit
Pin Function
c
Mute pin. Switches the transmitting signal
and the DTMF signal in the transmitting
system, and the receiving signal and the KT
signal in the receiving system (SW2 and
SW3 in the block diagram). When low, the
DTMF and KT signals are valid.

c
Transmission input amplifier + input.
Because bias voltage is not applied
internally, connect signal from REF (pin 61)
via a resistor.
c
Transmission input amplifier input pin.
c
Transmission input amplifier output pin.
59
TA IN
c
Input pin for LINE output pin.
60
DTMF IN
c
Input for DTMF input pin.
