Buffer circuit.

摘要

A buffer circuit, mainly comprised of a flip-flop (FF), is disclosed. The flip-flop receives an external input (ADD) via a first input circuit (IN,) and a reference voltage (REF) via a second input circuit (IN2), then produces internal complementary outputs (A,A) via an output circuit (OUT) which uses the bootstrap effect. The flip-flop cooperates with at least one level setting device (X) by way of the second input circuit (IN2). The level setting device functions to produce a voltage level (at N12) to de-activate the second input circuit (IN2) only during the activation of the flip-flop (with φ1 on).
