INFRAED REMOCON RECEIVER
INTRODUCTION
TheS5G9802X01 is a CMOS integrated circuit for the infrared ray
remote control transmitter function to be used with the KS9801
for receiver. It can be applied to TV, VCR, VDP, CDP and AV
controller.
The S5G9802X01 has 18 functions, and a total of 75 commands can
be transmitted. These commands are generated by continuous
keys with multiple keying and 12 commands by single shot keys.
16DIP300A
FEATURES
• Wide range of operating supply voltage :
VDD = 2.0V - 5V
• Low power consumption : IDS<1 m A at standby mode
• Containing ceramic oscillation circuit
• Function of multiple keying
• Adaptable to various models using custom code bits

FUNCTIONAL DESCRIPTION
1. OSCILLATION CIRCUIT
• The oscillation circuit is activated when any key is depressed. The ceramic resonator connected to XI, XO is
normally operated at 455kHz oscillation frequency.

2. KEY INPUT & STROBE OUTPUT
• All key input pins have a pull down resistor to VSS. 18 keys can be connected by key input K1 - K6 and 6x3
matrix by means of strobe signal ST1 - ST3.
• Multiple keying is possible for the keys connected to ST1 Line (key No. 1 - 6), and all depressed keys are
output (Output becomes continuous pulses).
• Among the strobe signal lines, priority is set in the order, ST1>ST2>ST3.
The keys connected to ST2 and ST3 lines have priority and when input is made through more than 2 keys, and
single signal is preferentially output in order of K1 - K6.
• Finally, the keys connected to ST2 and ST3 lines are for single signals and no second signal is transmitted
unless input is made again after the key is released once.
