The combination of code bits of S5G9802X01 and S5G9803X01 is shown in Table 2.

S5G9803X01 has CODE1 and CODE2 code terminals. Code bit of C3 has been pulled up in IC and C3 is always

kept at 1 status.

Therefore, on transmitter S5G9802X01 it is necessary to keep code bit C3 at 1.

To keep code bit C3 at 1, connect a diode to the Cci terminal from ST3 terminal.

3. If input voltage above VDD +0.3 V may be applied to the REMIN Input Terminal (2 PIN), connect about ten resis-

tors in series to the REMIN Input Terminal. (This is to prevent latch-up).
