4 / 16 page Single/Dual, +3V/+5V Dual-Speed Comparators with Auto-Standby 4 _______________________________________________________________________________________ ELECTRICAL CHARACTERISTICS (continued) (VCC = +2.7V to +5.25V, specifications are for high-speed mode, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1) CONDITIONS (Note 9) 10mV overdrive (Note 10) µs (Note 8) 3 tASB Auto-Standby Timeout tASBE UNITS MIN TYP MAX SYMBOL PARAMETER Auto-Standby Enable Time µs 24 tASD Auto-Standby Wake-Up Time 10mV overdrive (Note 11) (Note 12) µs 1.6 tPWD Auto-Standby Wake-Up Input or LP Pulse Width µs 0.8 tASCD Auto-Standby Comparator Disable (Note 13) µs 3 tLPE Low-Power Enable Time (Note 14) µs 1.1 4 tHSE High-Speed Enable Time (Note 15) µs 0.7 tLPCD Low-Power Comparator Disable (Note 16) ns 20 tLPSH Low-Power STAT_ High AUTO-STANDBY/LOW-POWER TIMING (Note 7; Figure 2) Note 7: Timing specifications are guaranteed by design. Note 8: Set by 1000pF external capacitor at the STO_ pin. tASB is defined as the time from last input transition to STAT_ = high. Does not include time to go into standby condition (tASBE). Note 9: tASBE is defined as the time from when STAT_ goes high to when the supply current drops to 5µA. Note 10: tASD is defined as the time from the last input transition to when STAT_ goes low. The comparator is in high-speed mode before STAT_ is low. Note 11: tPWD is defined as the minimum input or LP pulse width to trigger fast-mode operation from auto-standby. Note 12: tASCD is defined as the time from the last input transition to when the supply current increases to 300µA. Note 13: tLPE is defined as the time from when LP is driven high to when the supply current drops to 5µA. Note 14: tHSE is defined as the time from when LP goes low to when STAT goes low. The comparator is in high-speed mode before STAT_ is low. Note 15: tLPCD is defined as the time from when LP goes low to when the supply current increases to 300µA. Note 16: tLPSH is defined as the time from when LP goes high to when STAT_ goes high. ms 510 16 |
