DIN

Code Address Pin No. 0 ~ 5.

I

These six tri-state pins are detected by PT2270 to determine

the encoded waveform bit 0 ~ bit 5. Each pin can be set to “0”,

“1”, or “f” (floating).

Code Address Pin No. 6 ~ 11/Data Pin No. 5 ~ 0.

These six pins are used as higher address input bits or data

output pins depending on the version (type) of PT2270 used.

When used as address inputs, these pins are tri-state input pins

I/O

and each pin can be set to “0”, “1”, or “f” (floating).

When used as output pins, these pins are driven to VCC if (1) the

address decoded from the waveform that was received

matches the address setting at the address input pins, and (2)

the corresponding data bits received is a “1” bit. Otherwise,

they are driven to VSS.

Data Input Pin.

I The encoded waveform received is serially fed to

PT2270 at this pin.

I Oscillator Pin No.1 A resistor connected between these two

pins determine the fundamental

O Oscillator Pin No. 2 frequency of PT2270.

Valid Transmission.

O Active High Signal. VT in high state signifies that PT2270

receives valid transmission waveform.
