They have saturation voltage of 150mV at Ix = 15mA, so they can drive LEDs directly. GND ( #12 ) GROUND DEF ( #13 ) AFT DEFEAT OUTPUT This terminal is made of open collector transistor output through a resistor of 33082. It is used for AFT (Automatic Fine Tuning: TV use) defeat, sound muting and LED indicate erasing. CHD ( #15 ) CHANNEL DOWN INPUT Usually pulled up to Ve through a resistor, Channel selector changes at positive going edge of input signal of this terminal and the channel selector works orderly from K16 to K1. CHU ( #16 ) CHANNEL UP INPUT Usually pull up to Veg through a resistor, Channel selector changes at positive going edge of input signal of this terminal and the channel selector works orderly from K1 to K16. If CHU and CHD terminals put down to ground at same time, initial channel is selected. So, it is very useful to power on channel set or remote control operation use. These terminals include schmitt trigger circuit and this hysteresis level is controled by external resistors.

Typical oscillation frequency is 2kHz. (R= 68k, C= 0.022uF) KIN ( #18 ) KEY INPUT When channel selection key is pushed, as pushed channel is not selected, “High” level of signal is applied to this terminal through a potentiometer. Then channel selector scans terminals of K1~K16. And when sense up this terminal, it pull down the voltage of this terminal and stop the scanning. SKP ( #19 ) SKIP INPUT Usually pull up ta Vcc through resistor. When only 12 channels are used, conect terminals (K13~ K16) to this terminal.
