2. GMS37XXX
Description
The GMS37XXX series are remote control transmitter which uses CMOS technology.
This enables transmission code outputs of different configurations, multiple custom code
output, and double push key output for easy fabrication.
The GMS37XXX series are suitable for remote control of TV, VCR, FANS, Air-
conditioners, Audio Equipment, Toys, Games etc.
It is possible to structure the 8 x 7 key matrix for GMS37112, and the 4 x 7 key matrix
for GMS37004.
