HT6280
Car Alarm Decoder
Features
Operating voltage: 3V~5V
Low power dissipation and high noise im-
munity CMOS technology
A built-in oscillator with only a 5% resistor
312 trinary address codes
6 decoder control data outputs
General Description
The HT6280 is an 18-bit decoder CMOS LSI
designed for use in remote control car alarm
system. When complemented by one of the TE
triggered HT600/HT640/HT680 or DATA trig-
gered HT6187/HT6207/HT6247 encoder ICs
from a range of 318 series of encoders, a com-
plete remote car alarm system can be formed.
The details on the 318 encoders can be found in
the relevant databook encoder section.
3 local alarm trigger inputs:
TRIG, AL+, AL-
A valid transmission indicator (LED)
ACC disarms the whole car alarm system
Easily interface with an RF or an IR
medium
After receiving the 18 bits of information from
the encoder the HT6280 interprets the first 12
bits as address and the last 6 bits as control
signal data. If these received 12 bits of address
matches that of the locally set address then the
6 data bits are latched and the control function
executed. Three types of control function are
incorporated in the device, these are arm/dis-
arm, panic and power on/off. The HT6280 also
provides 3 momentary data outputs for other
user defined special purposes.
