Overview
The SN74CBT3125CRGYR is a quadruple FET bus switch manufactured by Texas Instruments. It operates with a supply voltage range of 4 V to 5.5 V and features low ON-state resistance of 12 Ohms maximum. The device provides -2 V undershoot protection and exhibits a maximum propagation delay of 150 ps. It is housed in a 14-VQFN package (3.5x3.5 mm) suitable for surface mount installation. The component supports a wide operating temperature range from -40°C to +85°C.
Feature Summary
- Quadruple FET bus switch architecture providing four independent signal paths
- -2 V undershoot protection capability for robust signal integrity
- Low ON-state resistance ensuring minimal signal attenuation
- High-speed performance with low propagation delay
Applications
- Portable equipment requiring high-density signal switching
- Consumer electronics utilizing TTL-compatible logic levels
- Computing products needing efficient bus isolation
- Telecommunications infrastructure components
Procurement Notes
Verify the specific suffix 'RGYR' corresponds to the 14-VQFN package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure storage conditions adhere to moisture sensitivity level requirements specified in the datasheet to maintain component reliability during assembly processes.
Selection Notes
Select this component for applications requiring quad-channel bus switching with tight timing constraints. The 14-VQFN package offers a compact footprint ideal for space-constrained designs. Verify that the system supply voltage remains within the 4 V to 5.5 V range to ensure proper operation and avoid exceeding absolute maximum ratings.
Part Context
This part belongs to the SN74CBT3125C family of high-speed TTL-compatible FET bus switches. The family is designed for low-voltage applications, offering superior performance compared to standard CMOS switches. The CRGYR designation specifically identifies the reel-packaged version in the QFN-14 form factor, distinguishing it from other packaging options like PW or DGQR.
Replacement Considerations
SN74CBT3125CPWRE4: Pin-compatible alternative in TSSOP-14 package. SN74CBT3125RGYR: Direct equivalent in QFN-14 package without E4 suffix. Verify pinout compatibility and thermal characteristics before substitution.
