IR-D14
14-Bit Infrared Remote Control Decoder IC
Quick & Easy - Infrared Remote Control
The IR-D14 IC is a custom pre-programmed microcontroller designed by Reynolds Electronics to
decode Sony Corporation’s infrared remote control command protocol. Add instant remote control
to your next robotics application, OEM products, or hobby projects with the IR-D14 and an “off-theshelf” inexpensive universal remote control transmitter.
Use the IR-D14 IC with any universal IR remote
control transmitter that supports the Sony IR
protocol for simple, and “instant” remote control
solutions. If you can program your IR remote
control transmitter to use the Sony IR data
protocol, you can control the IR-D14 IC.
The IR-D14 provides 14 individually controlled
digital outputs + one additional 15th bit as an
LED status indicator, and requires only a single
external component. The IR detector module.
IR transmitter buttons 1 through 0, channel up,
channel down, volume up, and volume down are
used to control the 14 individual IR-D14 digital
output pins shown in the table below.
A single 40KHz infrared detector module with
the IR-D14 IC completes the entire remote
control receiver assembly.
The IR-D14 ignores data received for buttons
not shown in the table - allowing unobtrusive
system range performance testing without
disturbing logic states of the 14 digital outputs.
The LED drive output can be used as a 15th
digital output providing a 15-bit IR decoder IC in
a single 18-pin DIP device package.
Include IR remote control in your next product,
robot, or home control project in minutes…!

14-Bit Infrared Remote Control Decoder IC
Operation:
On power-up the IR-D14 digital outputs default to logic 0 or ground. The LED drive output is “opencollector”, and defaults to high impedance to turn off the status LED. A valid button press received
from the universal IR transmitter corresponding to an IR-D14 digital output will toggle that outputs
logic state from ground to logic 1. Pressing the same button a 2nd time will toggle the same digital
output pin from logic 1 back to ground.
Depressing and holding a button on the transmitter will cause the corresponding output to toggle
between logic 1 to logic 0 at rates of approximately ½ second “500 millisecond” intervals.
Note: The open-collector LED output pin will toggle when any valid Sony IR data packet is
received, and will always return to the default high impedance state during idle, or non-transmit
periods.
The IR-D14 IC uses the internal oscillator of the microcontroller, requires no external oscillator or
crystal for operation, and the IR-D14 IC firmware is “self-tuning” to help reduce false digital output
triggers.
