Freq. Test Circuit, VS = 5V 3.0 MHz tR, tF Output Rise and Max. Freq. Test Circuit 15 ns Fall Times VS = 5V, CL = 10 pF tPD Trigger Propagation Delay VS = 5V, Measure Delay 100 ns from Trigger to Output (1) All voltages are measured with respect to the ground pin, unless otherwise specified. (2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not ensure specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not ensured for parameters where no limit is given, however, the typical value is a good indication of device performance. (3) If the RESET pin is to be used at temperatures of −20°C and below VS is required to be 2.0V or greater. 4 Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: LMC555 |
