Additional Infomation About Product

PCA9540B 2 2-channel I C-bus multiplexer Rev. 7.1 19 January 2018 Product data sheet 1. General description 2 The PCA9540B is a 1-of-2 bidirectional translating multiplexer, controlled via the I C-bus. The SCL/SDA upstream pair fans out to two SCx/SDx downstream pairs, or channels. Only one SCx/SDx channel is selected at a time, determined by the contents of the programmable control register. 2 A power-on reset function puts the registers in their default state and initializes the I C-bus state machine with no channels selected. The pass gates of the multiplexer are constructed such that the V pin can be used to DD limit the maximum high voltage that is passed by the PCA9540B. This allows the use of different bus voltages on each SCx/SDx pair, so that 1.8 V, 2.5 V or 3.3 V parts can communicate with 5 V parts without any additional protection. External pull-up resistors can pull the bus up to the desired voltage level for this channel. All I/O pins are 5 V tolerant. 2. Features and benefits 1-of-2 bidirectional translating multiplexer 2 I C-bus interface logic compatible with SMBus standards 2 Channel selection via I C-bus Power-up with all multiplexer channels deselected Low R switches on 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 testing is done to JEDEC Standard JESD78 which exceeds 100 mA Packages offered: SO8, TSSOP8, XSON8PCA9540B NXP Semiconductors 2 2-channel I C-bus multiplexer 3.
