Mô tả:
PT2249 - Remote Control Receiver IC
The PT2249A_PT2250A Series are infra-red remote control receivers utilizing CMOS Technology.
Remote Control System can be constructed together with the PT2248 remote control encoder. The
PT2249A Series are packaged in 16 pins DIP (PT2249A version is also available in SOP package) and
are capable of controlling 10 functions while the PT2250A Series are packaged in 24 pins DIP and are
capable of controlling 18 functions. Several options, inverting/non-inverting IR signal input and/or
dependent/independent cyclic (toggle) outputs, are provided to fit different application needs.

Thông số kỹ thuật:
CMOS technology
Low power consumption
Very high noise immunity
Able to output parallel multiple keying signals sent from the transmitter (PT2249A is able to output up to 5 functions simultaneously while PT2250A is able to output up to 6 functions simultaneously)
Outputs for single pulse, hold pulse and cyclic pulse are provided
A single terminal type oscillator by means of RC is provided
Code detection circuit prevents interference from various types of machines and apparatus
Digital filtering and code checking prevent interference from light sources such as PL lamp without sacrificing the receiving sensitivity

Ứng dụng:
Audio equipment remote control
Television (TV) remote control
Video Cassette Recorder (VCR) remote control
