Ground
Chip Disable
A logic low (< 0.8 V) sets normal operation. A logic high (> 2.0 V) disables the IC to con-
serve power. Input impedance is nominally 90 k
Supply voltage 2.8 to 7.0 V, approx. @ 1 mA
Receive level detector output on the microphone/speaker side
Receive level detector input on the microphone/speaker side
Positive control output for U4090B
Negative control output for U4090B
Response time
An RC at this pin sets the response time for the circuit to switch modes
It is a system ac ground, supplied by U4090B, V
An RC at this pin sets the time constant for the transmit background monitor
Transmit level detector input on the microphone/speaker side
Transmit level detector output on the microphone/speaker side, and input to the transmit
background monitor
