FUNCTION

Hook switch input.

HKS

HKS = 1: On-hook state. Chip in sleep mode, no operation.

HKS = 0: Off-hook state. Chip enabled for normal operation.

HKS pin is pulled to VDD by internal resistor.

N-channel open drain dialing pulse output (Figure 1). Flash key will

cause DP to be active in either tone mode or pulse mode.

DP/C4

DTMF

In pulse mode, remains in low state. In tone mode, outputs a dual or
