This device is designed to be used as an encoder in remote control applications. For the decoder component, see MC145027.
The MC145026 encodes nine lines of information and serially sends this information upon receipt of a transmit enable (TE) signal. The nine lines may be encoded with trinary data (low, high, or open) or binary data (low or high). The words are transmitted twice per encoding sequence to increase security.
Operating Temperature Range: -40 to +85°C
Very Low Standby Current for the Encoder: 300 nA Maximum @ 25°C
Interfaces with RF, Ultrasonic, or Infrared Modulators and Demodulators
RC Oscillator, No Crystal Required
High External Component Tolerance; Can Use ±5% Components
