very low power, very simple to use, very easy circuits
to build, and very effective.
Operating frequency: 40kHz
(works with 38/40kHz detectors)
Encoder IC Power requirement: 3 to 5VDC
Operating current (idle): < 1uA @ 3 or 5VDC
Key-Press (hold): 50uA @5VDC
Range: Up to 100' (with long-range driver circuit)
The new Tiny-IR-II transmitter IC
will run from 3 to 5 volts DC, and draws less than 1uA in sleep-mode while
waiting for a key-press.
The infrared LED can be
connected directly to the Tiny-IR-II encoder with a series limiting resistor,
or an optional high-power/long-range driver can be used to increase the LED output
for operating distance in excess of 100-foot.
The Tiny-IR-II transmitter uses a
carrier modulated pulse-drive technique for exceptional operating distances. Press a button,
data is sent. Release the button, and the transmitter goes into sleep-mode
drawing less than 1uA stand-by power for long lasting battery powered
Infrared Encoder/Transmitter IC
Low-Power/Short-Range Transmitter Option
High-Power/Long-Range Transmitter Option (cap optional)
Decoder IC works with 38 & 40KHz
Decoder IC Power requirement: Regulated +5VDC
Operating current (idle): < 1 mA @5VDC [No Load]
Output Operation: Latching
Output drive capacity: Source or sink 25mA per pin, 200mA total (all 5 output
Output pins default to logic
"0" (ground) when power is first applied, and toggle & latch when a valid
synch pulse & key-press data are received from the encoder IC.
Each valid data reception will toggle the output pins from "0" to "1" logic states
depending on the key pressed on the encoder IC input switches.
There are no address pins, and
no output pins are changed until the synchronization pulse & data are received
The Tiny-IR-II decoder outputs
differ dramatically from the drive outputs of decoder IC's such as the Holtek
allowing direct control of LEDs, solid-state relays, and other small DC loads
which can be driven
directly by Tiny-IR-II decoder outputs.
This is quite an improvement
over the standard remote control decoder ICs available on the market today,
and requires much less circuitry on the receiver section for a complete remote

Notice no external components are required except the IR
detector module to use the Tiny-IR-II decoder.
