APPLICATION INFORMATION
FUNCTION DESCRIPTION
When tone enable input is low, oscillator is inhibited, being allowed to low power standby mode
since transistor goes to
turn off state, so D0 ~ D3 input data is ignored.
However if tone enable input goes from low to high, input data is latched and tone output is enabled, and it is correspond
to data input.
This device is designed with 14 levels, 28 segments in each single-tone. The column tone is pre-emphasized 2dB than
the row tone.
