The PCA82C250 and PCA82C251 are advanced transceiver products for use in automotive and general industrialapplications with transfer rates up to 1 Mbit/s. They support the differential bus signal representation beingdescribed in the international standard for in-vehicle CAN high-speed applications ( ...

The PCA9541 is a 2-to-1 I2C-bus master selector designed for high reliability dual masterI2C-bus applications where system operation is required, even when one master fails orthe controller card is removed for maintenance. The two masters (for example, primaryand back-up) are located on separate I2C ...

The PCA9549 provides eight bits of high speed TTL-compatible bus switching controlledby the I2C-bus. The low ON-state resistance of the switch allows connections to be madewith minimal propagation delay. Any individual A to B channel or combination of channelscan be selected via the I2C-bus, determi ...

The PCA9546A is a quad bidirectional translating switch controlled via the I2C-bus. TheSCL/SDA upstream pair fans out to four downstream pairs, or channels. Any individualSCx/SDx channel or combination of channels can be selected, determined by thecontents of the programmable control register.

The PCA9555 is a 24-pin CMOS device that provides 16 bits of General Purpose parallelInput/Output (GPIO) expansion for I2C-bus/SMBus applications and was developed toenhance the NXP Semiconductors family of I2C-bus I/O expanders. The improvementsinclude higher drive capability, 5 V I/O tolerance, lo ...

The PCA9547 is an octal bidirectional translating multiplexer controlled by the I2C-bus.The SCL/SDA upstream pair fans out to eight downstream pairs, or channels. Only oneSCx/SDx channel can be selected at a time, determined by the contents of theprogrammable control register. The device powers up w ...

The PCA9548A is an octal bidirectional translating switch controlled via the I2C-bus. TheSCL/SDA upstream pair fans out to eight downstream pairs, or channels. Any individualSCx/SDx channel or combination of channels can be selected, determined by thecontents of the programmable control register.An ...

The PCA9557 is a silicon CMOS circuit which provides parallel input/output expansion for SMBus and I2C-bus applications. The PCA9557 consists of an 8-bit input port register, 8-bit output port register, and an I2C-bus/SMBus interface. It has low current consumption and a high-impedance open-dra ...

The P82B96 offers many different ways in which it can be used as abus interface. In its simplest application it can be used as aninterface between bus systems operating from different supplyvoltages. Opto isolation between two bus systems is possible, andalso the availability of the Tx and Rx signal ...

This module can be used to interface to the MMC card in MMC or * SPI modes. It supports a multiple card environment. The reset and * identification processes assume multiple cards on the bus. * In MMC mode, the card number is used as the RCA operand in the * commands.
