3,4,5,6,11,12,13,14ピン部分はLM1881とコンパチ。（とってもユニークなＩＣです。）
LM1881以外に下記の信号が出力される。

Function |
| 9 |
Level Output |
This pin provides an analog voltage which is nominally equal to twice the
sync pulse amplitude of the video input signal applied to pin 4. It therefore provides an
indication of signal strength. |
| 10 |
No Signal Detect Output |
This is a digital output which goes high when either a) loss of input
signal or b) the input signal level falls below a predetermined amplitude as set by RLV on
pin 2. There will be several horizontal lines delay before the output is initiated. |
| 15 |
Horizontal Sync Output |
This output produces only true H pulses of nominal width 5 ms. The leading
edge is triggered from the leading edge of the input H sync, with the same prop. delay as
the composite sync. The half line pulses present in the input signal during vertical
blanking are eliminated with an internal 2H eliminator circuit. |
