TIMING CHARACTERISTICS

(VCC = +1.65V to +5.5V, VL = +0.9V to +3.6V, VCC R VL, TS = VL, CVCC = 1FF, CVL = 0.1FF, CIOVL_ P 100pF, CIOVCC_ P 100pF, TA

= -40NC to +85NC, unless otherwise noted. Typical values are at VCC = +3V, VL = +1.2V and TA = +25NC. All timing is 10% to 90%

for rise time and 90% to 10% for fall time.) (Note 5)

Note 2: All devices are 100% production tested at TA = +25NC. Limits over the operating temperature range are guaranteed by

design and not production tested.

Note 3: VL must be less than or equal to VCC during normal operation. However, VL can be greater than VCC during startup and

shutdown conditions.

Note 4: VIHL, VILL, VIHC, and VILC are intended to define the range where the accelerator triggers.

Note 5: Guaranteed by design.

Note 6: External pullup resistors are required.
