74CBTLV3125DS,118

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74CBTLV3125DS,118 is a 4-bit bus switch housed in an SSOP16 (SOT519-1) package. It operates on a single supply voltage ranging from 2.3 V to 3.6 V and supports an ambient temperature range of -40 °C to +125 °C. The device features four independent switches with separate output enable inputs (1OE to 4OE). Key electrical parameters include a maximum propagation delay of 0.31 ns at 3.0 V to 3.6 V, a typical ON resistance of 5 Ω, and compliance with JEDEC standards JESD8-5 and JESD8-B/JESD36.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides rail-to-rail switching between two ports with low on-state resistance for minimal signal distortion.
• Includes IOFF circuitry that disables outputs during partial power-down to prevent damaging backflow currents.
• Features Schmitt trigger action at control inputs to ensure tolerance for slower input rise and fall times across the entire supply voltage range.

Signal Switches, Multiplexers, Decoders Applications

• High-speed data bus switching applications
• Partial power-down mode operations requiring isolation
• Mixed-signal environments needing controlled signal routing

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix ',118' corresponds to the SSOP16 package configuration when sourcing components. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Ensure design compatibility with the 2.3 V to 3.6 V supply voltage constraints before procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for designs requiring high-speed bidirectional data transfer with independent channel control. The SSOP16 package offers a compact footprint suitable for space-constrained PCB layouts. Consider the low ON resistance and fast propagation delay for maintaining signal integrity in high-frequency digital systems.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74CBTLV logic family, which focuses on low-voltage, high-speed bus switching solutions. The CBTLV series is designed to provide efficient signal routing with minimal power consumption. It complements other logic functions by offering robust switching capabilities within a standardized pinout architecture compatible with existing system designs.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for alternative packages such as TSSOP14 or DHVQFN14 if different form factors are needed. Verify functional equivalence regarding pinout and electrical characteristics before substituting with other 4-bit bus switches from the same or competing manufacturers.

Signal Switches, Multiplexers, Decoders FAQ

How does the device handle partial power-down scenarios?

The integrated IOFF circuitry automatically disables the outputs when the device is powered down, preventing potentially damaging backflow currents through the switch channels.

What is the function of the nOE input pins?

The nOE (output enable) inputs control the state of each switch. When nOE is HIGH, the switch enters a high-impedance OFF-state; when LOW, the switch connects the ports in an ON-state.
