General description
The PCA9545A/45B/45C is a quad bidirectional translating switch controlled via the I2C-bus. The SCL/SDA upstream pair fans out to four downstream pairs, or channels. Any individual SCx/SDx channel or combination of channels can be selected, determined by the contents of the programmable control register. Four interrupt inputs, INT0 to INT3, one for each of the downstream pairs, are provided. One interrupt output, INT, acts as an AND of the four interrupt inputs.M27C
An active LOW reset input allows the PCA9545A/45B/45C to recover from a situation where one of the downstream I2C-buses is stuck in a LOW state. Pulling the RESET pin LOW resets the I2C-bus state machine and causes all the channels to be deselected as does the internal power-on reset function.
Features and benefits
■ 1-of-4 bidirectional translating switches
■ I2C-bus interface logic; compatible with SMBus standards
■ 4 active LOW interrupt inputs
■ Active LOW interrupt output
■ Active LOW reset input
■ 2 address pins allowing up to 4 devices on the I2C-bus
■ Alternate address versions A, B and C allow up to a total of 12 devices on the bus for larger systems or to resolve address conflicts
■ Channel selection via I2C-bus, in any combination
■ Power-up with all switch channels deselected
■ Low Ron switches
■ Allows voltage level translation between 1.8 V, 2.5 V, 3.3 V and 5 V buses
■ No glitch on power-up
■ Supports hot insertion
■ Low standby current
■ Operating power supply voltage range of 2.3 V to 5.5 V
■ 5 V tolerant Inputs
■ 0 Hz to 400 kHz clock frequency
■ ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101
■ Latch-up protection exceeds 100 mA per JESD78
■ Three packages offered: SO20, TSSOP20, and HVQFN20
