All temperature limits are guaranteed by design. Note 2: Guaranteed by design. Note 3: tRD timeout period begins after POK1 timeout period (tPOKP) and VCC2 ≥ VTH2 (max) (MAX6741/MAX6744). Note 4: Refers to the manual reset function obtained by forcing the RESET output low. Note 5: VCC1 ≥ 1.6V. Typical Operating Characteristics (TA = +25°C, unless otherwise noted.)
