SN74CB3Q3125RGYR

Overview

The SN74CB3Q3125RGYR is a quadruple FET bus switch in a 14-pin VQFN package. It operates on a single supply voltage ranging from 2.3V to 3.6V and supports data I/O signaling levels up to 5.5V. The device features four independent bidirectional switches with active-low output enable inputs. Key electrical parameters include a typical ON-state resistance of 4Ω, a maximum propagation delay of 0.2ns at 3.3V, and an input/output capacitance of 4pF when off. It supports partial-power-down modes via the Ioff feature.

Feature Summary

High-bandwidth data path supporting frequencies up to 500MHz
Rail-to-rail switching capability for data ports across specified voltage ranges
Low ON-state resistance characteristics maintained over the operating temperature range
Integrated undershoot clamp diodes on data and control inputs

Applications

USB interface connections
Differential signal interfaces
Bus isolation circuits
Low-distortion signal gating

Procurement Notes

Verify the specific suffix 'RGYR' corresponds to the 14-pin VQFN package with tape-and-reel carrier. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly planning. Ensure design compatibility with the recommended operating conditions regarding supply voltage and thermal dissipation requirements.

Selection Notes

Select this component for applications requiring low insertion loss and minimal signal distortion in high-speed digital buses. The charge pump mechanism ensures flat ON-state resistance, making it suitable for rail-to-rail signal transmission. Verify that the control logic levels are compatible with TTL or CMOS outputs driving the OE pins.

Part Context

This part belongs to the SN74CB3Q3125 family of low-voltage, high-bandwidth bus switches manufactured by Texas Instruments. The RGYR designation specifically identifies the VQFN package variant with reel packaging. It serves as a signal routing element within complex electronic systems requiring efficient data path management.
