Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix '-55' against official Diodes Incorporated documentation, as standard datasheets list 'PI3DBS16412ZLCEX'. Confirm if this suffix denotes a specific tape-and-reel quantity or packaging variant. Ensure compliance with RoHS 3 directives and lead-free definitions when sourcing. Cross-reference the manufacturer part number with authorized distributors to confirm availability and exact specifications.

Analog Switches - Special Purpose Selection Notes

Select the PI3DBS16412ZLCEX variant when a 40-pin TQFN package (3x6 mm) is required for space-constrained designs. Choose this component for systems requiring bi-directional switching of up to eight differential channels at speeds up to 20 Gbps. Consider the 3.3 V supply requirement and industrial temperature range (-40°C to +85°C) during system integration. Evaluate the low insertion loss characteristics for maintaining signal integrity in high-speed data paths.

Analog Switches - Special Purpose Part Context

The PI3DBS16412 belongs to the PI3DBS series of high-speed mux/demux switches from Diodes Incorporated, formerly Pericom Semiconductor. This family is designed for flexible signal routing in modern computing and storage infrastructure. The ZLCEX designation specifically identifies the 40-contact TQFN package option within the product line, distinguishing it from the 42-contact ZHEX variant.
