CBT3253PW,112

Signal Switches, Multiplexers, Decoders Overview

The Nexperia CBT3253PW,112 is a dual 1-of-4 high-speed TTL-compatible FET multiplexer/demultiplexer housed in a TSSOP16 plastic thin shrink small outline package (SOT403-1). 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 a typical ON-resistance of 5 Ω at VCC = 4.5 V and VI = 0 V, with a maximum propagation delay of 0.25 ns. Control inputs are overvoltage tolerant up to 5.5 V.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP16 package variant when sourcing components. Confirm that the required operating temperature range aligns with the specified -40 °C to +85 °C limits. Ensure design compatibility with the 4.5 V to 5.5 V supply voltage requirements before procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for applications requiring low propagation delay and direct TTL interfacing. The dual configuration allows independent control of two separate 1-of-4 paths. Consider the TSSOP16 package dimensions if board space is constrained. Verify that input signals remain within the overvoltage tolerance limits of the control pins.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the Nexperia CBT series, which specializes in bus switches and analog switches. The CBT family utilizes advanced BiCMOS technology to provide high-speed switching capabilities with minimal power consumption. These devices are designed for hot-plug applications and isolation tasks where low on-resistance is critical.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The CBT3253D is available in an SO16 package as a pin-compatible alternative. Verify package dimensions and lead pitch differences when substituting between TSSOP and SO variants.
