Abstract: A circuit includes an input terminal, an output terminal and a latch. The input terminal receives an input signal. The latch is programmable with a value. The latch communicates the input signal to the output terminal in response to the circuit not being in a sleep mode and in response to the circuit being in the sleep mode, furnishes a second signal to the output terminal indicative of the value.

Abstract: Power saving method is achieved by weakly holding a signal line in its last in time state, which is responsive to and may be overcome by the state of an external signal. During sleep mode, the weakly held signal line state tracks and holds the external signal using alternatively a controllable weak pull-up or pull-down device, such that weakly held state may be driven to a different state by the external driving signal with slight power consumption. When sleep mode is off, the keeper function is disabled and the signal line maybe driven alternatively internally or externally depending upon the state of an enable line.

Abstract: A buffer driver, driving signals with edge transitions onto a transmission line is controlled to improve slew rate and glitch termination by controlling the driver to have a low impedance during a period when edge transitions are taking place, and upon cessation of edge transitions, controlling the driver to have a high impedance.

Abstract: A supply bounce controlled output buffer circuit for producing an output signal at an output terminal pin with a significant reduction in inductive ringing includes an output stage, a first delay network (38), and a second delay network (42). The output stage includes a series-connected pull-up transistor (P1) and pull-down transistor (N1) coupled between a first power supply terminal pin and a second power supply terminal pin. The common connection of the pull-up and pull-down transistors (P1, N1) are coupled to an output terminal pin. The first delay network (38) is interconnected between the first power supply terminal pin and a control electrode of the pull-up transistor (P1) for turning off the pull-up transistor (N1) so as to slow down the rate of rise of the output signal for a portion of the time when the output terminal pin is making a low-to-high transition so as to reduce the overshoot.
