Product details

Bus switch for signal isolation and hot-swap

The Texas Instruments SN74CB3Q16244DGGR is a 4-channel bus switch, each channel providing a 1:1 connection path. It acts as a low-impedance analog switch for isolating or connecting digital and analog signals on a PCB, commonly used in hot-swap interfaces, memory bank switching, and signal routing in telecom or industrial backplanes. The four independent circuits let you gate separate data buses from a single device, reducing component count versus discrete FETs.

Lifecycle and compliance

Status is Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect. For BOM planning, this part remains a safe selection for new designs and production runs without imminent obsolescence risk.

Frequently asked questions

What is the difference between SN74CB3Q16244DGGR and SN74CB3Q16244DGG?

The difference is in the packaging and reel format. The DGGR suffix indicates Tape & Reel (TR) and Cut Tape (CT) options, while the DGG suffix typically refers to tube packaging. The silicon and electrical characteristics are identical.

What is the equivalent or alternate for SN74CB3Q16244DGGR?

No direct pin-compatible second source is listed in the available records. The DS90CP22MT/NOPB is a crosspoint switch, not a bus switch — different circuit topology and function. For a functional equivalent, look for other 4-channel 1:1 bus switches in the 74CB or 74CB3Q family with matching supply range and package.
