PCA9543A_43B v.8 20140403 Product data sheet - PCA9543A_43B v.7
Modifications:
• Figure 6 “Control register” updated: corrected label above bits [7:4] from “(read only)”
to “(read/write) but reads back chip status; bit 6 and bit 7 always read 0”
• Section 6.2.1 “Control register definition”: added second paragraph
• Section 6.2.2 “Interrupt handling”:
– Table 7 “Control register: Read — interrupt” corrected: bits [7:6] corrected from “XX” to
“00” (for both channel 0 and channel 1)
– ‘Remark’ paragraph: added second sentence
• 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.”
• Table 10 “Static characteristics at V
DD
=2.3V to 3.6V”, Table note [2]: inserted phrase “for
at least 5 s”
• Table 11 “Static characteristics at V
DD
= 4.5 V to 5.5 V”, Table note [2]: inserted phrase “for
at least 5 s”
