The ADM4850 / ADM4851 / ADM4852 / ADM4853 / ADM4854 /ADM4855 / ADM4856 / ADM4857 are differential line transceiverssuitable for high speed, half-duplex and full duplex data communication on multipoint bus transmission lines. Theyare designed for balanced data transmission and comply with EIA Standards RS-485 and RS-422. The ADM4850 / ADM4851 / ADM4852 / ADM4853 are half-duplex transceivers that sharedifferential lines and have separate enable inputs for the driver and receiver. The full duplex ADM4854 / ADM4855 / ADM4856 / ADM4857 transceivers have dedicated differential line driveroutputs and receiver inputs.The devices have a 1/8-unit load receiver input impedance, which allows up to 256 transceivers on one bus. Because only onedriver must be enabled at any time, the output of a disabled or powered down driver is three-stated to avoid overloading the bus.The receiver inputs have a true fail-safe feature, which ensures a logic high output level when the inputs are open or shorted.This guarantees that the receiver outputs are in a known state before communication begins and when communication ends.The driver outputs are slew rate limited to reduce EMI and data errors caused by reflections from improperly terminated buses.Excessive power dissipation caused by bus contention or by output shorting is prevented with a thermal shutdown circuit.The devices are fully specified over the commercial and industrial temperature ranges and are available in 8-lead SOIC (ADM4850through ADM4857), 8-lead LFCSP (ADM4850 / ADM4852 / ADM4853), and 8-lead MSOP (ADM4850 only) packages.Applications Low power RS-485 applications EMI sensitive systems DTE to DCE interfaces Industrial control Packet switching Local area networks Level translators

The ADP5589 is a 19 channel GPIO (General Purpose Input/Output) port expander with built-in keypad matrix decoder, programmable logic, reset logic, and PWM generator. The IC is capable of handling QWERTY size keyboards and GPIO expansion. I/O expander ICs are used in portable devices (phones, remote controls, & cameras) and non-portable applications (healthcare, industrial & instrumentation). I/O expanders can be used to increase the number of I/Os available to a processor or to reduce the number of I/Os required through interface connectors for front panel designs.The ADP5589 handles all key scanning and decoding and can flag the main processor via an interrupt line that new key events have occurred. GPI changes and logic changes can also be tracked as events via the FIFO, eliminating the need to monitor different registers for event changes. The ADP5589 is equipped with a FIFO to store up to 16 events. Events can be read back by the processor via an I2C-compatible interface.The ADP5589 frees up the main processor from having to monitor the keypad, thereby reducing power consumption and/or increasing processor bandwidth for performing other functions. The programmable logic functions allow common logic requirements to be integrated as part of the GPIO expander, saving board area and cost. Reference software Linux driver is available.APPLICATIONS Devices requiring keypad entry and I/O expansion capabilities
