Abstract
A programmable output driver is comprised of a first signal path for pulling an output node up to a first voltage level and a second signal path for pulling the output node down to a second voltage level. A plurality of capacitors and a plurality of switches are provided for programmably connecting certain of the plurality of capacitors to the second signal path to control the falling edge of a signal output from the driver. In a preferred embodiment, the first signal path includes a boot circuit which primarily controls the leading edge of the signal output from the driver. A method of operating an output driver is also disclosed.
