BL9148 General Description
The BL9148 is CMOS LSI developed for use n the general infrared ray remote control transmitter. The circuit has 10 functions ombining with BL9149 while it has 18 functions combining with BL9150.And total 75 commands can be transmitted: 63 commands by continuous keys, as multiple keying is possible, and 12 commands by single-shot keys.
BL9148 Features
Wide range of operating supply voltage (VDD=2.2~5.5V)
CMOS structure assures extremely low power dissipation
Multiple Keying is possible.
Less external parts
Adaptable to other models as code bits are available.
An oscillator can be constructed only by connecting an LC or ceramic resonator.
