CBT3253ADS,118

Signal Switches, Multiplexers, Decoders Overview

The Nexperia CBT3253ADS,118 is a dual single-pole, 4-throw bus switch (multiplexer/demultiplexer) in an SSOP16 package. It operates at a supply voltage of 4.5 V to 5.5 V with TTL-compatible inputs. The device features two output enable inputs and two select inputs to route signals between A and B terminals. Key electrical parameters include a typical ON resistance of 5 Ω at 5 V, propagation delay up to 6.2 ns, and ESD protection exceeding 2000 V HBM. It functions within an ambient temperature range of -40 °C to +85 °C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix '118' against official Nexperia documentation to confirm tape and reel packaging details. Ensure the SSOP16 package variant matches the design footprint requirements. Confirm that the non-automotive qualification status aligns with the target application environment before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for designs requiring low ON resistance and minimal propagation delay in a 5 V logic environment. The SSOP16 package offers a compact solution for space-constrained PCB layouts. Verify input voltage compatibility with the system's logic levels and ensure adequate thermal management for the specified power dissipation limits.

Signal Switches, Multiplexers, Decoders Part Context

The CBT3253A series belongs to Nexperia's Cross Bar Technology (CBT) family, designed for high-speed signal switching. This specific model integrates two independent 1-of-4 switches into a single 16-lead package. It serves as a functional alternative to similar bus switches from other manufacturers, providing robust ESD protection and low on-state resistance for reliable data transmission.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Compatible substitutes include SN74CBT3253 from Texas Instruments. Verify pinout compatibility and electrical specifications such as ON resistance and propagation delay when cross-referencing datasheets.
