Abstract: An integrated circuit includes an input pad and a Schmitt trigger coupled to the input pad. The Schmitt trigger includes a main PMOS branch that charges an intermediate node of the Schmitt trigger responsive to voltage transitions at the input node. The Schmitt trigger includes a charging assistance circuit that helps to rapidly charge the intermediate node of the Schmitt trigger. The charging assistance circuit includes a parallel PMOS branch in parallel with the main PMOS branch.

Abstract: An integrated circuit includes an output pad, and I/O driver that drives data to the output pad, and a predriver that controls the I/O driver. The integrated circuit includes maximum voltage generator that receives a first supply voltage and a second supply voltage and outputs to the predriver a maximum voltage corresponding to the higher of the first supply voltage and the second supply voltage.

Abstract: A serial peripheral interface (SPI) device includes a serial clock (SCK) pad receiving a serial clock, first and second Schmitt triggers directly electrically connected to the SCK pad to selectively respectively generate first and second clocks in response to rising and falling edges of the serial clock, first and second flip flops clocked by the first and second clocks to output bits of data to a data node, a multiplexer having an input coupled to the data node and an output coupled to driving circuitry, and driving circuitry transmitting data via a master-in-slave-out (MISO) pad.
