DESCRIPTION OF OPERATION -
SETTING OF ATTENUATION
As for the TC9176/77P, optional attenuation level data should be input from the DATA,
CK and ST terminals. This data consists of 20 bits.
(The TC9176P has no loudness control and therefors, the 3rd bit must be always at "L"
level).

17ths 20th bits are chip select bits and both the TC9176P and TC9177P are selected -
only by (0001)' and is never operated by other than (0001).
The infinite attenuation level ls set by data of ...78dB. Therefore, one step up
from the infinity becomes .-76dB. Every change to data that has been taken in ls

The TC9176/77P is generally operated by (+) and (-) power supplies.
Owing to the built-in level shifter, the DATA, CK and ST terminals are operated by (+)
power supply only. The Input inverter for there 3 terminals have low input threshold
voltage and therefore, there terminals 'operate at 5V logic level.

LOUDNESS FUNCTION (TC9177P)
The TC9177P is provided with the loudness taps.
LOUDNESS 0N
When 3rd bit of data ls set to "I", the loudness switch LSl is turned 0N and L82 is
turned OFF, outputting -20 dB attenuation level to Loudness-1 and Loudness-2 terminals.
When a high/lov-pass boost circuit ls added externally to Loudtusss-1 and Loudness-2
terminals, it becomes possible to control loudness to -20dB or below.
