Description
The 4LD model is an IC chip belonging to the electronic component category, specifically designed for infrared remote control systems. With a total of 448 commands divided into 7 sub-system groups, each with 64 commands, it allows for accurate and efficient transmission of infrared signals. It can be configured via a press button, slider switch or hard-wired, and generates pattern for driving the output stage. The patterns are pulse distance coded, and the mode of transmission is determined in conjunction with the sub-system address.
Specifications and features
- 7 sub-system addresses
- Up to 64 commands per sub-system address
- High-current remote output at VDD=6V (- IOH=80mA)
- Low number of additional components required
- Key release detection by toggle bits
- Very low stand-by current (< 2µA)
- Operational current < 1mA at 6V Supply
- Supply voltage range 2 to 6.5V
- Ceramic resonator controlled frequency (typ. 450kHz)
Application Scenarios
The 4LD IC chip can be used in any electronic device requiring infrared remote control capabilities. It is particularly useful in devices requiring the transmission of a large number of commands, such as televisions, sound systems, or other home entertainment devices.
Comparison
Advantages- Supports a total of 448 commands, divided into 7 sub-system groups with 64 commands each, allowing for efficient and accurate transmission.
- Minimal additional components required to operate the IC chip
- Key release detection by toggle bits allows for greater control over transmission
- Very low standby current (< 2µA) allows for energy efficiency and cost savings.
Disadvantages- Flashed pulses require a wide-band preamplifier within the receiver, which may increase cost and complexity of implementation
