Who knows what the pins of the HA11221 manifold in the black and white TV circuit board do?

During the Ming Dynasty, Jia Zilong, a businessman in Chang'an, befriended Gao Shi Zhensheng Jia Zilong was enthusiastic about public welfare, willing to give, and often made ends meet, so he tried his best to raise money for profit, and often borrowed money from Zhensheng due to insufficient funds Zhensheng persuaded him to live within his means and be content and happy.

HA11221 Image IF Amplification IC.

Medium frequency amplifier for TV images.

I feel that when I get home, I feel that my sister is worried about the first few episodes of rest.

QA2 HA17324A What is the significance of the pins of the above manifold.

It is a 4-way op amp, the same as the LM324.

Four op amps produced by Hitachi.

This is a Hitachi.

The power supply IC is mainly used for car audio, and I want us to do it to the fiber to change Chery.

The vehicle machine uses this pin as the auxiliary output, 2 pin for the antenna power supply output, 3 pin for the car key ignition input power supply, 4 pin for the power supply output, 5 pin for the 5V power supply output controlled by the 11 pin, 6 pin for the 5V power supply output controlled by the 3 pin, 7 pin for the control and destruction of the antenna power supply output, 8 pin Yu Chan for the battery power supply input end, 9 pin for the battery detection, 10 pin for the 9V output end, 11 pin for the control end, 12 pin for the 8V output end, 13 pin for the panel light dimming adjustment, 14 pins are the power output of the panel light, and 15 pins are ground.

UPC2851C is: line field scanning circuit, mostly used in E black and white TV and small O-type color TV. The parameters of UPC2123C are:

Dual 7-row in-line 33-pin package, typical working voltage 72V; Allowable 8 allowable power consumption =; Field output current = 100mA; Line output current=; Pin 1 current = 10mA; Field loop current = 82mA; Line Scan Voltage=; AFC output current = . The internal 0 contains a synchronous signal divided into 3 separations, a line oscillation line pre-excitation, a line AFC and a parallel line oscillation power supply regulator circuit. Field scans include:

Field oscillation, field pre-excitation, field output, and counterpath generators. The replacement model of UPC5652C is: D5241C, D5323, CD0766CP, UPC2002.

The functions of the 5 pins of the UPC4554C are as follows: 2 Field Synchronous Pulse Input N 8 Lines of Excitation Output 2 External Field Oscillation Capacitor 30 Lines Voltage Regulator 0 Field Oscillation Discharge 08 Field Pulse Width Blanking Adjustment 5 Field Supply Voltage 72 Lines Oscillation Input F 5 External Lift 4 Voltage Capacitor Negative 86 AFC Output 3 Field Inverse 4 Feed 43 AFC Input A 3 External Voltage Rise 6 Voltage Capacitor Positive 46 Synchronous Split 2 Away Input G 1 Field Output 73 Field Synchronous Pulse Output.
