Positive supply input
Tone enable input. An internal pull-up resistor is in a chip. When this pin connects to
logic ‘low’, the oscillator is inhibited and the tone generators and output transistor are
turned off. A low to high transition on this pin latches in data from D0 ~ D3, and tone
generation continues until this pin is connected ‘low’ again.
Single tone enable. An internal pull-up resistor is in a chip. When this pin connects
to logic ‘low’, the device is in a single tone mode. For normal operation, connects this
pin to V
DD
or open-circuit.
Group selection input. This pin is used to select the high group or low group fre-
quency, when the device is in single tone mode. An internal pull-up resistor is in a
chip. When this pin connects to V
DD
or open, the high group will be generated, and when
connects to V
SS
, the low group will be generated.
Negative supply input
Oscillator input
Oscillator output
N-channel open drain output.
This pin is a logic high state, when the tone enable pin is a high state.
This pin goes a logic low state, when the tone enable pin is a low state.
DATA-INPUTS. These are the inputs for binary-coded data, which is latched in on
the rising edge of the tone enable signal.
No connection.
This output is the open emitter of a NPN transistor. When an external load resistor
is connected from this pin to V
SS
, the tone generates on the tone enable pin = ‘High’.
