The PCA9540BDP,118 from NXP Semiconductors is a 1-of-2 bidirectional translating multiplexer designed for I2C-bus control. It allows an upstream I2C-bus pair to fan out to two downstream pairs, enabling channel selection via a programmable control register. This device supports voltage level translation between different bus voltages, such as 1.8 V, 2.5 V, 3.3 V, and 5 V, without additional protection, as all I/O pins are 5 V tolerant.
Key electrical features include an operating power supply voltage range of 2.3 V to 5.5 V and compatibility with SMBus standards. The multiplexer supports clock frequencies up to 400 kHz. It is designed for hot insertion and has no glitch on power-up. ESD protection exceeds 2000 V HBM and 1000 V CDM, with latch-up testing exceeding 100 mA.
The PCA9540BDP,118 is supplied in an 8-TSSOP package suitable for surface mounting. The device powers up with all multiplexer channels deselected, and a power-on reset function initializes the registers to their default state.
