NEVB-NCA9548A_NCA9547 - 8-channel I²C switch and multiplexer evaluation board
The NEVB-NCA9548A_NCA9547 evaluation board is a compact platform for evaluating Nexperia’s 8-channel I2C switch and multiplexer devices. It supports the NCA9548A with multiple active channels and the NCA9547 with one active channel at a time and RESET capability. The board provides easy access to upstream and downstream I2C buses, jumper-selectable address and reset control, dedicated test points, and support for Fast-mode I2C up to 400 kHz.
Key features & benefits
- Operating power supply voltage range of 1.65 V to 5.5 V
- 1-of-8 bidirectional translating switches
- Allows voltage level translation between 1.8 V, 2.5 V, 3.3 V and 5 V buses
- Active LOW reset input
- Three address pins allowing up to eight devices on the I²C-bus≡
- Low ISTANDBY below 1µA reduces the static power consumption
- High OFF-state isolation preventing signal leakage and interference between channels.
- ΔICC (additional supply current) of 3µA reduces the power consumption.
- Low RON of 10Ω
- Glitch-free power-up and supports Hot insertion
- Supports SM and FM frequency modes
- Specified from -40 °C to +85 °C and -40 °C to +125 °C
