STMicroelectronics SR1
The SR1 has one Smart Reset input (SR) with preset delayed Smart Reset setup time (tSRC). The reset output (RST) is asserted after the Smart Reset input is held active for the selected tSRC delay time. The RST output remains asserted either until the SR input goes to inactive logic level (i.e.| Part No. | SR1 |
