PCA9545A_45B_45C v.9 20140505 Product data sheet - PCA9545A_45B_45C v.8
Modifications:
• Section 6.4 “Power-on reset”, first paragraph, third sentence corrected from “Thereafter,
V
DD
must be lowered below 0.2 V to reset the device.”
to “Thereafter, V
DD
must be lowered below 0.2 V for at least 5 s in order to reset the
device.” (this is a correction to documentation only; no change to device)
• Table 8 “Static characteristics at V
DD
= 2.3 V to 3.6 V”: Table note [2] corrected by inserting
phrase “for at least 5 s” (this is a correction to documentation only; no change to device)
• Table 9 “Static characteristics at V
DD
= 4.5 V to 5.5 V”: Table note [2] corrected by inserting
phrase “for at least 5 s” (this is a correction to documentation only; no change to device)
