概述
Description
NB3V1104CMTTBG is a four-channel digital buffer/voltage-level translator IC used to connect signals between two voltage domains in mixed‑voltage designs. It provides four independent translation/buffer channels (two rails: VCCA and VCCB) and is commonly used to interface low‑voltage microcontrollers with peripherals operating at a different voltage. The TT/BG suffixes denote packaging and RoHS/green-material variants (e.g., tape-and-reel, specific package type). Typical uses include I2C, SPI, and general GPIO level shifting. For exact electrical specs (rail voltages, propagation delay, input/output thresholds, and current limits) consult the manufacturer’s datasheet. If you share the vendor or a link, I can pull the precise details.
