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.","metaTitle":"SN74CB3Q16244DGGR Bus Switch, 4 x 1:1, 48-TSSOP","metaDescription":"TI SN74CB3Q16244DGGR bus switch, 4 independent 1:1 circuits, 2.3V-3.6V supply, -40°C to 85°C, 48-TSSOP.

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."},{"question":"What is the equivalent or alternate for SN74CB3Q16244DGGR?","answer":"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.
