CBT3245ADS,118

Signal Switches, Multiplexers, Decoders Overview

The CBT3245A is an octal bus switch manufactured by Nexperia, designed for partial power-down applications. It features a single output enable input (OE) controlling eight switch channels, which are disabled when OE is HIGH. The device provides a 5 Ω switch connection between two ports and supports direct interface with TTL levels. It includes IOFF circuitry to prevent damage during partial power-down states. The component operates within a supply voltage range of 4.0 V to 5.5 V and an ambient temperature range of -40 °C to +85 °C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Supports partial power-down mode operation via integrated IOFF circuitry
• Provides overvoltage tolerant control inputs up to 5.5 V
• Features high electrostatic discharge protection exceeding specified standards
• Enables direct interfacing with TTL logic levels

Signal Switches, Multiplexers, Decoders Applications

• Partial power-down system architectures
• TTL level signal routing
• Octal bidirectional data bus switching

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific package variant required, as the datasheet lists TSSOP20 and DHVQFN20 options. Confirm that the ordering suffix matches the desired thermal or lead-free specifications. Ensure the design accounts for the non-automotive qualification status if used in automotive environments. Cross-reference the latest product status on the manufacturer's website before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for designs requiring low ON resistance and robust ESD protection. Consider the available packages based on board space constraints. Verify compatibility with the target supply voltage range of 4.0 V to 5.5 V. Ensure the application does not require automotive qualification, as this product is not certified for such use.
