SN74CBT1G125DCKT

Overview

The SN74CBT1G125DCKT is a single bus switch manufactured by Texas Instruments, housed in a SC-70-5 surface-mount package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40°C to 85°C. The device functions as a non-inverting buffer with three-state output capability, designed for low-voltage applications requiring efficient signal routing.

Feature Summary

• Single-channel bus switching architecture
• Three-state output control
• Low on-resistance performance

Applications

• Portable equipment signal routing
• Consumer electronics data buses
• Communication systems interface management

Procurement Notes

Verify the specific suffix DCKT corresponds to the SC-70-5 package configuration. Confirm the 4.5V to 5.5V supply requirement aligns with system design constraints. Ensure the -40°C to 85°C industrial temperature rating meets environmental specifications. Cross-reference datasheet revision G for accurate electrical characteristics.

Selection Notes

Select this component when a single-channel, low-voltage bus switch is required for 5V logic systems. The SC-70-5 package suits space-constrained designs. Verify that the 3-state output functionality matches the system's tri-state bus requirements. Consider the industrial temperature range for broader operational environments compared to commercial grades.

Part Context

This part belongs to the Texas Instruments 74CBT series of low-voltage bus switches. It provides high-speed signal switching capabilities for digital systems. The device integrates a single channel with independent control, offering compact integration for modern electronic designs requiring efficient data path management.

Replacement Considerations

SN74LVC1G125DCK3: Different voltage range (1.65V–5.5V). SN74AHCT1G125DCKT: Higher voltage range (4.5V–5.5V), different logic family. SN74CBT1G125DC: Same function, different package (SC-70-5 vs SC-70-5, verify suffix). SN74CBT1G125DCKT: Direct match.
