Description

The SC9149A/SC9150A are CMOS LSIs designed to be used on an infrared remote control receiver. When this LSI is used in combination with the SC9148A transmitter, a remote control system can be constructed. The SC9149A is a DIP-16 type and can control up to 10 functions, while the SC9150A is a DIP-24 type that can control up to 18 functions.

Specifications and features

• Able to output parallel multiple keying signals sent from the transmitter (The SC9149A is able to output parallel up to 5 functions, while the SC9150A is able to output parallel up to 6 functions.)
• Output for single pulse, hold pulse, and cyclic pulse are provided. (cyclic pulse is available only for SC9150A)
• A single terminal type oscillator by means of CR is provided.
• Code detection circuit provided for code check with the transmitter prevents interferences from various types of machines and apparatus.

Application Scenarios

The SC9149A/SC9150A are typically used in devices that require remote controls, such as televisions, DVD players, audio systems, and other entertainment systems.

Comparison

• Capable of controlling multiple functions, making it ideal for use in various electronic devices.
• Provides outputs for single pulse, hold pulse, and cyclic pulse.
• Has a code detection circuit that prevents interference from other machines or apparatus.

• The SC9149A can control only up to 10 functions, while the SC9150A can control up to 18 functions.
• The SC9150A is larger in size due to the DIP-24 packaging.
