PCA9544A v.4

Modifications:

• Section 2 “Features and benefits”, 16th bullet item: deleted phrase “200 V MM per JESD22-A115”

• Table 1 “Ordering information”: added “Topside marking” column

• Table 2 “Ordering options”: added “Orderable part number”, “Packing method”, and “Minimum order

quantity” columns

• Table 4 “Control register: Write — channel selection; Read — channel status”: value for INT0,

command ‘channel 3 enabled’ corrected from “0” to “X” (correction to documentation only;

no change to device)

• Section 6.4 “Power-on reset”, first paragraph, third sentence: corrected from “VDD must be lowered

below 0.2 V to reset the device” to “In order to reset the device, VDD must be lowered below 0.2 V

for at least 5

s.” (correction to documentation only; no change to device)

• Table 6 “Limiting values”: added limiting value “Tj(max)”

• Added (new) Section 10 “Thermal characteristics”

• Table 8 “Static characteristics at VDD = 2.3 V to 3.6 V”:

– Table note [2]: inserted phrase “for at least 5

s”

– subsection “Select inputs A0 to A2, INT0 to INT3”: Max value for VIH corrected from

“VDD + 0.5 V” to “6 V” (correction to documentation only; no change to device)

• Table 9 “Static characteristics at VDD = 4.5 V to 5.5 V”:

– Table note [2]: inserted phrase “for at least 5

s”

– subsection “Select inputs A0 to A2, INT0 to INT3”: Max value for VIH corrected from

“VDD + 0.5 V” to “6 V” (correction to documentation only; no change to device)

• Figure 15 “Definition of timing on the I2C-bus” updated (added 0.3  VDD and 0.7  VDD reference

lines)

• Added Section 15 “Soldering: PCB footprints”
