IO buffers and ESD protection

SPI, QSPI, uWire, and general purpose CMOS input-output buffers with separate ESD protection or self-protected, with or without hysteresis, deglitching, duty-cycle correction, edge detection, fixed or programmable strength, etc.
I2C input-output buffers fully compliant to Philips specification for all speeds: Normal, Fast, and High-Speed (clock frequencies up to 0.1, 0.4, and 3.4 MHz respectively). Featuring hysteresis, 10 or 50 ns deglitching, slew-rate limiting, self-ESD protected.
LVDS input-output buffers with programmable strength for optimizing power consumption for given connection length and load impedance, with or without equalization and signal conditioning.
USB input-output buffers fully compliant to USB 2.0 specification.
Any other customer-specific input and output buffers.
