SN74CBT3245AGQNR TI Bus Switch | 20-BGAMICROSTARJUNIOR（4X3） | 8-Bit, 5V

Product Overview

The SN74CBT3245AGQNR is a high-performance 8-bit bus switch from Texas Instruments (TI), designed for bidirectional voltage translation and signal routing in digital systems. Housed in a compact 20-pin BGA MICROSTAR JUNIOR (4x3 mm) package, it offers low on-state resistance (5 Ω typical) and wide voltage range (4.5 V to 5.5 V), making it ideal for bus isolation, level shifting, and hot-swap applications. The device features two ports (A and B) with independent control via the output-enable (OE) pin, ensuring minimal propagation delay and low power consumption.
