Active high tri-state output, detect for 350 Hz.
Active high tir-state ooutput, detect for 400/620 Hz.
(See Note.)
Active high tri-state output, detect for 440 Hz.
Active high tri-state output, detect for 480 Hz.
Active high tri-state output, detect for 425 Hz.
Active high enabled, when low drives STROBE low.
Active high input. When low tri-stateDETnpins.
Analog signal input (internally capacitive coupled).
Active high output, indicates valid DET n.
Most positive power supply input pin.
Internally generated mid-power supply voltage
(output).
Most negative power supply input pin.
Buffered oscillator output (3.58 MHz).
Crystal oscillator or digital clock input.
Crystal oscillator output. Used only with a crystal.
Use X358 when clock output signal is required.
Active low input. Adds 10 dB of gain to input stage.
Compatibility selection. Connection to VSS selects
400 Hz detection. (M-981-02 emulation.) Connection
to V
DD
or no connection selects 620 Hz detection.
Power-down operation, logic high inhibits internal
clock. Internal pulldown resistor.
