CBT3125PW,118

Signal Switches, Multiplexers, Decoders Overview

The Nexperia CBT3125PW,118 is a quadruple FET bus switch housed in a TSSOP14 package (SOT402-1). It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +85 °C. The device features four independent line switches with TTL-compatible input levels. Key electrical characteristics include a typical on-resistance of 5 Ω at 4.5 V and propagation delay of 0.25 ns. It provides robust ESD protection exceeding 2000 V (HBM) and latch-up performance exceeding 500 mA per JESD78.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix matches the required package type and tape/reel configuration. Confirm that the component meets RoHS compliance requirements for your manufacturing process. Ensure design reviews account for the specified operating temperature range and absolute maximum ratings to prevent device stress during operation.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when designing circuits requiring multiple independent bidirectional switches with fast switching speeds. The TTL-compatible inputs simplify interface logic without additional level shifting. Consider the TSSOP14 package dimensions for PCB layout constraints and thermal management requirements relative to the expected current load.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the CBT3125 family of quadruple FET bus switches manufactured by Nexperia. It serves as a solution for managing data flow in digital systems where signal integrity and speed are critical. The PW suffix indicates the TSSOP14 plastic thin shrink small outline package variant.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct replacements must match the quadruple FET bus switch functionality and TSSOP14 package. Verify pinout compatibility and electrical parameters such as on-resistance and propagation delay before substitution.

Signal Switches, Multiplexers, Decoders FAQ

How is the switch state controlled?

Each switch is disabled when its associated output enable (nOE) input is HIGH. A LOW signal on nOE activates the ON-state, allowing data transfer between ports.

What is the maximum supply voltage?

The recommended operating condition specifies a maximum supply voltage (VCC) of 5.5 V. The absolute maximum rating allows up to 7.0 V.
