The MAX7319 2-wire serial-interfaced peripheral features eight input ports with selectable internal pullups, overvoltage protection to +6V, and transition detection with interrupt output.All input ports are continuously monitored for state changes (transition detection). Transitions are latched, allowing detection of transient changes. Any combination of inputs can be selected using the interrupt mask to assert the active-low INT output. When the MAX7319 is subsequently accessed through the serial interface, any pending interrupt is cleared.The +5.5V tolerant active-low RST input clears the serial interface, terminating any I²C communication to or from the MAX7319.The MAX7319 uses two address inputs with four-level logic to allow 16 I²C slave addresses. The slave address also enables or disables internal 40kΩ pullups in groups of four ports.The MAX7319 supports hot insertion. All eight input ports, the serial interface SDA, SCL, AD0, AD2, active-low INT, and active-low RST remain high impedance in power-down (V+ = 0) with up to +6V asserted on them.The MAX7319 is one device in a family of pin-compatible port expanders with a choice of input ports, open-drain I/O ports, and push-pull output ports.The MAX7319 is available in 16-pin QSOP and 16-pin TQFN packages, and is specified over the automotive temperature range (-40°C to +125°C).ApplicationsCell PhonesNotebooksSAN/NASSatellite RadioServers

The MAX7325 2-wire serial-interfaced peripheral features 16 I/O ports. Ports are divided into eight push-pull outputs and eight I/Os with selectable internal pullups and transition detection. Eight ports are push-pull outputs and eight I/Os may be used as a logic input or an open-drain output.

The MAX9248/MAX9250 digital video serial-to-parallel converters deserialize a total of 27 bits during data and control phases. In the data phase, the LVDS serial input is converted to 18 bits of parallel video data and in the control phase, the input is converted to 9 bits of parallel control data. The separate video and control phases take advantage of video timing to reduce the serial-data rate. The MAX9248/MAX9250 pair with the MAX9247 serializer to form a complete digital video transmission system. For operating frequencies less than 35MHz, the MAX9248/MAX9250 can also pair with the MAX9217 serializer.The MAX9248 features spread-spectrum capability, allowing output data and clock to spread over a specified frequency range to reduce EMI. The data and clock outputs are programmable for a spectrum spread of ±4% or ±2%. The MAX9250 features output enable input control to allow data busing.Proprietary data decoding reduces EMI and provides DC balance. The DC balance allows AC-coupling, providing isolation between the transmitting and receiving ends of the interface. The MAX9248/MAX9250 feature a selectable rising or falling output latch edge. ESD tolerance is specified for ISO 10605 with ±10kV Contact Discharge and ±30kV Air-Gap Discharge.The MAX9248/MAX9250 operate from a +3.3V ±10% core supply and feature a separate output supply for interfacing to 1.8V to 3.3V logic-level inputs. These devices are available in a 48-lead LQFP package and are specified from -40°C to +85°C or -40°C to +105°C.ApplicationsIn-Vehicle Entertainment SystemsLCD DisplaysNavigation System DisplaysVideo Cameras
