Note 1: All devices are 100% tested at TA = +25°C. 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.
