Abstract
Official abstract text for this publication.
An output driver and a data output driving circuit using the output driver includes a pull-up driver including at least three pull-up transistors connected between a high voltage and an output node in a stack structure of three stages or more and a pull-down driver including at least three pull-down transistors connected between a ground node and the output node in a stack structure of three stages or more.
First claim
Opening claim text (preview).
What is claimed is: 1. An output driver comprising: a pull-up driver including first, second and third transistors of a first conductivity type connected by a cascade structure between a voltage supply node and an output node; and a pull-down driver including first, second and third transistors of a second conductivity type are connected by a cascode structure between a ground node and the output node, wherein a first high voltage, a first power supply voltage and a ground vol…
