CBT3245AD,112

Signal Switches, Multiplexers, Decoders Overview

The CBT3245AD,112 is an octal bus switch manufactured by Nexperia USA Inc. It features eight single-throw switch channels controlled by a single output enable input (OE). The device provides a 5 Ω connection between ports and supports partial power-down applications via IOFF circuitry. Recommended operating conditions specify a supply voltage range of 4.0 V to 5.5 V. Static characteristics indicate an ON resistance maximum of 15 Ω at VCC = 4.5 V with II = -15 mA. Dynamic performance includes a propagation delay maximum of 0.25 ns at VCC = 5.0 V.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific package designation against current official documentation before procurement. The 'AD' suffix indicates a SOIC-20 package variant which may have been superseded or removed in recent datasheet revisions. Confirm availability status directly with the manufacturer or authorized distributors as product lifecycles change frequently.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when designing systems requiring low on-resistance switching between two ports. Ensure the application operates within the recommended 4.0 V to 5.5 V supply voltage range. Verify that the required ESD protection levels meet JESD22 standards for your specific environment.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the CBT3245A family of octal bus switches from Nexperia. The family utilizes CMOS technology to provide high-speed signal switching with minimal power consumption. The series is designed for applications requiring bidirectional data transfer between different voltage domains.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check the datasheet revision history regarding package availability. The CBT3245AD (SOIC-20) was removed in later revisions; verify if CBT3245APW (TSSOP-20) is the intended replacement.
