Abstract:
An improved output driver circuit for a semiconductor integrated circuit device is provided. The output driver circuit receives a type select signal (.phi.1, /.phi.1) determined by bonding selection. When a heavy load circuit is connected to an output terminal (DQ), a signal (.phi.1) of low level and a signal (/.phi.1) of high level are provided, whereby transistors (18, 19) are turned on simultaneously in response to a data signal (Mo). When a light load circuit is connected to the terminal (DQ), a signal (.phi.1) of high level and a signal (/.phi.1) of low level are provided, whereby transistors (18, 19) are turned on at a different timing. More specifically, following charging of a light load by a transistor (18) having low mutual conductance, a transistor (19) is turned on. Therefore, noise generation can be flexibly suppressed by bonding selection.
