Package

The LDS3985M18R is packaged in a 18-pin TSSOP (Thin Shrink Small Outline Package). This compact package type is designed for efficient space utilization on printed circuit boards while providing good thermal performance.

Pinout

The LDS3985M18R is a high-performance dual 8-channel analog multiplexer/demultiplexer, housed in a 18-pin TSSOP package. It features 8 input/output lines (labeled A1 to A8 and B1 to B8) for signal routing, along with two select lines (S1 and S2) that control the selection of the input channels.
The pin count is 18, and the main functions include enabling or disabling the multiplexing operation via the enable pin (EN), with additional pins for power supply (VCC and GND). The device is designed for low power consumption and high-speed switching, making it suitable for various applications in data acquisition and signal routing.
In summary, the pin configuration includes:
- 8 channel inputs/outputs for each of the two multiplexers (A1-A8, B1-B8)
- 2 select lines (S1, S2)
- 1 enable pin (EN)
- 2 power supply pins (VCC, GND)
This structure allows for flexible signal multiplexing in electronic systems.
