PI3USB14-ALE+CX

Analog Switches - Special Purpose Overview

The PI3USB14-ALE+CX is a low voltage, high bandwidth USB 2.0 multiplexer/demultiplexer manufactured by Diodes Incorporated. It features two channels with four inputs each and three-state outputs controlled by a single enable pin. The device operates on a 3.3V supply voltage within an industrial temperature range of -40°C to +85°C. Key electrical parameters include a typical propagation delay of 0.3 ns, a -3dB bandwidth of 815 MHz, and an on-resistance of 5 Ω. It offers ESD protection rated at ±8 kV (HBM) and supports hot insertion capabilities.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and lead-free status. The 'ALE' designation indicates a 16-pin TSSOP package, while the '+CX' suffix typically denotes tape and reel packaging. Ensure compatibility with your assembly requirements before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits that require low latency switching for USB 2.0 or similar high-bandwidth interfaces. The single enable control simplifies logic design compared to multi-enable alternatives. Consider the 16-pin TSSOP package constraints regarding board space and thermal management during the layout phase.
