[{"type":"text","content":" PLANO, Texas--(BUSINESS WIRE)--\nDiodes Incorporated (Nasdaq: DIOD) has announced 16-bit PI4IOE5V6416Q and 34-bit PI4IOE5V6534Q bidirectional voltage-level translation general-purpose I/O (GPIO) expanders for automotive applications. Representing an industry first for the automotive industry, the automotive-compliant, AEC-Q100 Grade 2 qualified devices with dual voltage rail provide enhanced programmable I/O for next-generation low voltage microprocessors and microcontrollers via the I2C interface.\n\nAs part of Diodes' ongoing expansion into the automotive industry, the new devices provide engineers with a simple solution when additional I/Os are needed while keeping interconnections to a minimum - for example, in ADAS, telematics, and infotainment. Removing the need for an external voltage-level translator simplifies the design of new ADAS and telematics systems, and reduces BOM cost.\n\nBoth devices operate from 1.65V to 5.5V on the GPIO port side. On the SCL/SDA side (I2C interface), the PI4IOE5V6416Q operates from 1.65V to 5.5V and the PI4IOE5V6534Q from 0.8V to 3.6V. This dual power rail allows the devices to interface with next-generation low-power microchips on the SCL/SDA side. The expanders offer an exceptionally low standby current consumption of 1.5µA at 5V and 1µA at 3.3V for the PI4IOE5V6416Q and 2µA at 3.3V for the PI4IOE5V6434Q.\n\nEach 16- or 34-bit GPIO on these devices is configurable, and each port features a programmable pull-up or -down resistor and a programmable output current. Unlike many I/O expanders, the PI4IOE5V6416Q and PI4IOE5V6534Q also provide programmable open-drain outputs as part of the enhanced I/O features. The devices have an interrupt masking feature, enabling the designer to mask the interrupt from an individual GPIO port and initiate a system-level action.\n\nThe 16-bit PI4IOE5V6416Q is packaged in a 24-pin TSSOP, and 34-bit PI4IOE5V6534Q is available in the W-QFN4565-46 package. Both devices support PPAP documentation and are manufactured in IATF 16949 certified facilities. The unit price for the 16-bit PI4IOE5V6416Q is $1.80 in 3,000 piece quantities and $2.40 for the 34-bit PI4IOE5V6534Q in 3,500 piece quantities.\n\nAbout Diodes Incorporated\n\nDiodes Incorporated (Nasdaq: DIOD), a Standard and Poor's SmallCap 600 and Russell 3000 Index company, delivers high-quality semiconductor p...
