Output (V): SEPARATE OUTPUT

The separate output configuration allows for independent signal routing, providing flexibility and customization in signal distribution.

Maximum Seated Height: 0.539 mm

The low seated height enables a compact and space-saving design, ideal for applications with limited vertical space.

Width (mm): 2.36 mm

The narrow width of 2.36mm saves space on the circuit board, allowing for more components to be placed in a smaller area.

Other IC type: SPDT

The SPDT type allows for single-pole double-throw switching, providing versatility in signal routing and control.

Minimum Supply Voltage (Vsup): 1.65 V

The low minimum supply voltage ensures compatibility with low-power systems, making this product suitable for energy-efficient applications.

Maximum On-state Resistance (Ron): 12 ohm

With a maximum on-state resistance of 12 ohms, this product offers efficient signal transmission and minimal loss during operation.

Maximum Switch-on Time: 500 ns

The fast switch-on time of 500 nanoseconds ensures quick response and minimal signal delay, enhancing system performance.

Length: 2.36 mm

The compact length of 2.36mm contributes to a smaller overall footprint on the circuit board, maximizing space efficiency.

Maximum Switch-off Time: 90 ns

The short switch-off time of 90 nanoseconds ensures rapid signal cutoff, improving signal integrity and reducing interference.

Temperature Grade: INDUSTRIAL

The industrial temperature grade ensures reliable operation in harsh industrial environments, making this product suitable for rugged applications.

No. of Channels: 4

With 4 channels, this product can support multiple signal paths or configurations, providing versatility and flexibility in signal routing.
