HT12B - Encoder

Download the HT12B datasheet PDF. This datasheet also covers the HT12C variant, as both devices belong to the same encoder family and are provided as variant models within a single manufacturer datasheet.

Description

The 2 12 encoders are a series of CMOS LSIs for remote control system applications.

N data bits.

Each address/data input can be set to one of the two logic states.

Features

  • Operating voltage:.
  • 2.4V~5V for the HT12A/B/C.
