On-state resistance is determined by the lower of the voltages on the two (A or B) ports. (3) Specified by design (4) Δron = ron(max) – ron(min) measured at identical VCC, temperature, and voltage levels (5) This parameter is characterized, but not production tested. (6) Flatness is defined as the difference between the maximum and minimum values of on-state resistance over the specified range of conditions. (7) Ioff is the same as IS(off) (off-state switch leakage current). 4 Submit Documentation Feedback Copyright © 2003–2012, Texas Instruments Incorporated Product Folder Link(s): SN74LVC1G3157 |
