VRC/TX1

I/O
Function 1 VRC (valid received code) output and function 1 encode enable. In the decode mode,
VRC/TX1 is an output that goes to a logic-low state (for one frame — 768 clocks) when the device
receives the correct 40 bits of security code and function data (4 bits) matching function 1. In the
encoder mode, VRC/TX1 is an input that initiates the encoding of function 1 and output of function 1
data. When VRC/TX1 is pulled to GND, the device continuously outputs the function-1 code sequence
stored in EEPROM memory from DIN/DOUT up to 360 times. The device cannot transmit function-1
code again until VRC/TX1 is again pulled to GND. VRC/TX1 has an internal pullup resistor in both the
encoder and decoder modes, and switch debouncing in the encoder mode.

Function 2 VRC (valid received code) output and function 2 encode enable. In the decode mode,
VRC/TX2 is an output that goes to a logic-low state (for one frame — 768 clocks) when the device
receives the correct 40 bits of security code and function data (4 bits) matching function 2. In the
encoder mode, VRC/TX2 is an input that initiates the encoding of function 2 and output of function 2
data. When VRC/TX2 is pulled to GND, the device continuously outputs the function-2 code sequence

encoder and decoder modes, and switch debouncing in the encoder mode.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: Voltage values are with respect to GND.
