Product specification
Multistandard pulse/tone repertory
diallers/ringers
PCD3332-2; PCD3332-3;
PCD3332-S
In the on-hook mode or power-down mode of the
PCD3332-3, the keyboard I/Os are set to HIGH except
ROW 5 which is set to LOW. In this instance, depression
of the HOOK key can be detected by the external
hardware circuitry and converted to an active HIGH signal
which is passed to CE in order to ‘wake-up’ the
PCD3332-3.
When the HOOK key has been accepted the PCD3332-3
enters the hands-free mode.
ROW 5 was used to detect the HOOK key, this function is
deleted.
ROW 5 is an open-drain input, this configuration is used to
avoid current flowing in the on-hook mode or power-down
mode. A pull-up resistor should be connected to ROW 5.
The keyboards which the PCD3332-2, PCD3332-3 and
PCD33332-S support are shown in Figs 6, 7 and 8
respectively. The figures also show the diode options as
‘dotted’ keys.
