Datasheet for Texas Instruments SN74CBTLV3125 Quadruple FET Bus Switch, detailing specifications, ratings, and package options.
The SN74CBTLV3125 is a quadruple FET bus switch with independent line switches. Each switch is disabled when its output‑enable (OE) input is high, and the device supports partial‑power‑down operation using the Ioff feature, which prevents back‑flow current when power is removed.
The data sheet provides absolute maximum ratings, recommended operating conditions, electrical characteristics, switching performance, and detailed package information for multiple package options (DBQ, DGV, NS, PW, RGY, etc.). Mechanical drawings, tape‑and‑reel dimensions, and ordering information are also included.
| Supply voltage range (VCC) | -0.5 V to 4.6 V |
|---|---|
