PCA9540B规格书详情
DESCRIPTION
The PCA9540B is a 1-of-2 bi-directional translating multiplexer, controlled via the I2C-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.
A power-on reset function puts the registers in their default state and initializes the I2C state machine with no channels selected.
FEATURES
• 1-of-2 bi-directional translating multiplexer
• I2C interface logic; compatible with SMBus standards
• Channel selection via I2C-bus
• Power up with all multiplexer channels deselected
• Low RdsON 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 stand-by current
• Operating power supply voltage range of 2.3 V to 5.5 V
• 5 V tolerant Inputs
• 0 to 400 kHz clock frequency
• ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115 and 1000 V per JESD22-C101
• Latch-up testing is done to JESDEC Standard JESD78 which exceeds 100 mA
• Packages Offered: SO8, TSSOP8
