The PCA9545APW,118 from NXP Semiconductors is a versatile 4-channel I2C-bus switch designed for bidirectional translation. It allows for flexible channel selection through its I2C interface, enabling communication between different voltage buses, including 1.8 V, 2.5 V, 3.3 V, and 5 V parts without additional protection.
This device features four active LOW interrupt inputs and one active LOW interrupt output, simplifying system monitoring. It includes an active LOW reset input for recovery from bus issues and supports hot insertion. The operating supply voltage ranges from 2.3 V to 5.5 V, with all I/O pins being 5 V tolerant. The switch supports clock frequencies up to 400 kHz.
The PCA9545APW,118 is available in a 20-TSSOP package and is designed for surface mount applications. Its robust design includes ESD protection exceeding 2000 V and latch-up protection exceeding 100 mA.
