An input circuit that recognizes (e.g., buffers) logic level signals (e.g., of an input signal) represented by voltage levels that are lower than a supply voltage of an input circuit, and that exhibits static current draw immunity during stable states of an input signal. In one or more examples, series inverters are provided to buffer an input node and an output node of the input circuit. A voltage domain at the input circuit or output node may be higher than a voltage domain at the input node. Power supply to a first inverter of the series inverters may be turned OFF at least partially responsive to an indication that an output signal is a logic high; and power supply to the first inverter of the series inverters may be turned ON at least partially responsive to an indication that the output signal is a logic low. A third inverter may be maintained utilizing an input signal voltage to detect a falling edge of the input signal and turn ON power supply to the first inverter at least partially responsive thereto.

Recognizing transistor-transistor logic levels (TTL) at an input circuit with increased immunity to static current draw

Some embodiments of the present disclosure relate to a system that may include a replaceable module and a user device. The replaceable module may include an element and a one-wire authentication element in parallel with the element. The user device may be configured for operable coupling with the replaceable module. The user device may include a power source configured to provide power to the element, an authentication unit configured to perform a verification process for verifying authenticity of the replaceable module, and a signal conditioning unit arranged in a communication path between the one-wire authentication element and the authentication unit.

The present subject matter provides a system and a method for detecting liquid water. The method includes establishing signal communication between an RFID tag and an RFID reader, monitoring the signal communication between the RFID tag and the RFID reader and determining that liquid water is disposed between the RFID tag and the RFID reader or on the RFID tag if the signal communication between the RFID tag and the RFID reader is disrupted, interrupted or terminated.
