 Forum: General CCS C Discussion Posted: Mon Nov 13, 2006 12:11 pm Subject: Solved my own problem... |
| I've learned the important lesson of adding extra delays after writing to the MPS23S08 when using it as an output latch. When writing to the latch I only had to add an extra delay and everything work ... | |

Forum: General CCS C Discussion Posted: Mon Jun 28, 2004 6:41 am Subject: Found switching anomaly with the FET |
| I found a potential problem. When the FET switches to the OFF state,
there is a -0.740 V transient that lasts for approximately 70 nanoseconds. Could this negative going switching transient be eno ... |
