NOTES:
1. All voltages are referenced to ground.
2. Measured with VCC ≥ 2.7 volts.
3. Measured with RESET output open for TC1275/6; measured with RESET output open for TC1277.
4. tR = 5 s.
5. A 1k
external resistor may be required in some applications for proper operation of the microprocessor reset control circuit
when using the TC1276.
