Princeton Technology Corp.'s PT2461 and PT2462 are remote control transmitters utilizing CMOS Technology specially designed for infrared applications. They are compatible with LC7461M and LC7462M respectively and are capable of controlling 32 function keys and 3 double keys. PT2461 is housed in a 24-pin SO or DIP package and provides 13 bits of Custom Code while PT2462 is available in a 20-pin SO or DIP package and provides 8 bits of Custom Code.
The PT2461 and PT2462 are infrared remote control transmitters built with CMOS technology. PT2461 is offered in a 24‑pin SO or DIP package and provides a 13‑bit custom code, while PT2462 comes in a 20‑pin SO or DIP package with an 8‑bit custom code. Both devices support up to 32 function keys, three double‑key functions, and can store up to 64 external custom codes (PT2461). The transmitters operate over a wide voltage range of 1.8 V to 5.5 V and feature an on‑chip oscillator that can be driven by an external ceramic resonator.
These transmitters are used in a variety of consumer electronics such as DVD players, audio equipment, televisions, VCRs, audio cassette decks, and air conditioners. Ordering information includes multiple part numbers for different package options, and the devices are compatible with the LC7461M and LC7462M driver ICs.
