CBT3245APW,118

Signal Switches, Multiplexers, Decoders Overview

The CBT3245APW,118 is an octal bus switch manufactured by Nexperia. It features eight single-throw switch channels controlled by a single output enable input (OE). The device supports partial power-down applications through integrated I_OFF circuitry, which disables outputs to prevent damaging backflow currents when the device is powered down. It offers direct interface with TTL levels and includes overvoltage tolerant control inputs rated up to 5.5 V. The component is specified for operation across a temperature range of -40 °C to +85 °C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides eight independent switch channels for bidirectional data transfer between ports.
• Includes I_OFF circuitry to support partial power-down mode operations safely.
• Features overvoltage tolerant control inputs compatible with 5.5 V signals.

Signal Switches, Multiplexers, Decoders Applications

• Partial power-down system architectures requiring safe isolation during low-power states.
• Bidirectional bus switching in digital logic circuits interfacing with TTL levels.
• Data routing applications where overvoltage tolerance on control lines is required.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify current availability status as production lifecycle changes may affect supply. Confirm package type and tape/reel specifications match design requirements. Check for obsolescence notices from Nexperia. Ensure ESD handling procedures are followed during assembly. Validate that the specific suffix corresponds to the desired packaging configuration.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for designs requiring high-density octal bus switching with low on-resistance. Consider the I_OFF feature if the system utilizes partial power-down modes to reduce standby current. Verify that the control voltage levels remain within the 5.5 V tolerance limit. Ensure the operating temperature range meets the environmental constraints of the target application.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the CBT3245A family of octal bus switches from Nexperia. These devices are designed for high-speed data routing in digital systems. The family emphasizes low power consumption and robust protection features. The APW suffix typically indicates a TSSOP-20 surface-mount package variant suitable for automated assembly processes.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include other CBT3245A variants with different package suffixes such as CBT3245ADB or CBT3245APW,112. Verify pin compatibility and electrical parameters before substitution. Ensure the replacement part supports the same I_OFF functionality and voltage tolerances.
