STMicroelectronics SR2
The SR2 has two combined delayed Smart Reset™ inputs (SR0, SR1) with preset delayed Smart Reset™ setup time (tSRC). The reset output is asserted after both of the Smart Reset™ inputs were held active for the selected tSRC delay time. A 0.1 µF decoupling ceramic capacitor is 6 VCC Supply voltage recommended to be connected between VCC and VSS pins, as close to the SR2 device as possible Figure 3.| Part No. | SR2 |
