NTE7413

NTE7413 Integrated Circuit TTL − Dual 4−Input Positive NAND Schmitt Trigger Description: The NTE7413 is a dual 4−Input NAND Schmitt trigger in a 14−Lead plastic DIP type package. The device is temperature−compensated and can be triggered from the slowest of input ramps and still give clean, jitter−free output signals.
