  • Patent number: 11068434
    Abstract: Logic circuitry packages for association with replaceable print apparatus components are disclosed herein. An example logic circuitry package includes a timer and a serial data bus interface including a data contact and a clock contact, the serial data bus interface to interface with a serial data bus of a printer. The example logic circuitry package also includes logic circuitry to, in response to a first command sent to the logic circuitry package via the serial data bus of the printer: initiate a low voltage on the data contact; wait for a time period tracked by the timer to expire, without reference to a clock signal at the clock contact from the serial data bus; and upon expiration of the time period, cause the data contact to assume a second voltage different than the low voltage. The first command specifies a duration of the time period and the example logic circuitry is to maintain the low voltage on the data contact based on the duration of the time period.
