CAT1832 TOL selects 10% (TOL = GND) or 20% TOL = VCC) trip point tolerance. 4 8 GND Ground 5 9 RESET Active HIGH reset output. RESET is active 1. If VCC falls below the reset voltage trip point 2. If PBRST ¯¯¯¯¯¯ is low 3. If ST ¯¯ is not strobed low before the timeout period set by TD expires. 4. During power-up. 6 11 RESET Active LOW reset output.

These are stress ratings only, and functional operation of the device at these or any other conditions outside of those listed in the operational sections of this specification is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability. |
