Abstract
An output buffer includes a pull-up circuit and a pull-down circuit for driving widely varying capacitive and inductive loads without significant output ringing. The pull-up circuit includes a first pull-up transistor (N2), a NAND logic gate (42) and a second pull-up transistor (P2). The pull-down circuit includes a first pull-down transistor (P3), a NOR logic gate (38) and a second pull-down transistor (N3). Output impedance is increased and energy stored in parasitic inductance is decreased by the pull-up and pull-down transistors so as to reduce significantly the inductive ringing while accelerating output transitions.
