HT12E 12-Bit Encoder IC (HT12E IC) DIP-18 Package

Description

HT12E is a CMOS technology-based 12-bit Encoder. It is generally used with RF communication system applications. 12-bit Encoders can encode up to 2^12 two-state data which is transmitted via RF transmitter to receiver. This encoded data consists of 8 address bits and 4 data bits. For proper communication, HT12E is should be used with HT12D in the same address and data formate. This device consists of one data output pin that transmits the encoded data from the RF transmitter channel. Two oscillators pin (OSC1, OSC2) can decide the oscillation frequency of the Encoder by using an oscillator resistor. Active Low Trigger Enable pin (TE’) can trigger the transmission or vice versa.

The HT12E ICs have an operating range of VCC from 2.4 V to 12 V. Maximum current consumption is 0.3 mA through Icc and output sink and source current is 1.6 mA. The recommended operating voltage is 5 V.
