The CMOS output buffer (10) includes a pull-up device (112) and a pull-down device (114) connecting in series between a voltage source and a ground. A fast-rise/slow-fall inverter (116) is connected between an input line (118) and a gate of the pull-up device. A slow-rise/fast-fall inverter (120) is connected between the input line and a gate of the pull-down device (114). The fast-rise/slow-fall inverter (116) switches a signal from a low voltage level to a high voltage level faster than the slow-rise/fast-fall (120) inverter switches the signal from the low voltage level to the high voltage level. |
