A small computer system interface (SCSI) driver circuit having a programmable slew rate comprises N cascaded delay cells each including a data bit input, a delayed data bit output that communicates with the data bit input of an adjacent one of the N cascaded delay cells, and a delay time input that receives a programmable delay time value for setting a variable delay between receiving data at the data bit input and generating the delayed data bit output. N predrivers receive an output enable signal and a corresponding one of the N delayed data bit outputs and generate a predriver output signal based on the output enable and the corresponding one of the N delayed data bit outputs. N drivers have inputs that receive predriver output signals from corresponding ones of the N predrivers. An output port communicates with outputs of the N drivers.
