• The format of this data sheet has been redesigned to comply with the new identity
guidelines of NXP Semiconductors.
• Legal texts have been adapted to the new company name where appropriate.
• Table 3 “Pin description”:
– added Table note [1] and its reference at HVQFN16 pin 6
– changed naming convention for pins I/On to “IOn”
• Figure 7 “I/O Write mode (output)”: changed symbol “t_pv” to “t_v(Q)”
• Figure 8 “I/O Read mode (input)”:
– changed symbol “t_ph” to “t_h(D)”
– changed symbol “t_ps” to “t_su(D)”
• Table 4 “Limiting values”:
– changed symbol “V_CC” to “V_DD”
– changed parameter for I_SS from “supply current” to “ground supply current”
– changed symbol “P_O” to “P/out”
– changed parameter for T_amb from “operating temperature” to “ambient temperature”;
placed “operating” in Conditions column
• Table 5 “Static characteristics”:
– added reference to Table note [1] at I_OL in sub-section “I/O expander port”
• Table 6 “Dynamic characteristics”:
– sub-section “I²C-bus timing”: changed symbol/parameter from “t_SW, tolerable spike
width on bus” to “t_SP, pulse width of spikes that must be suppressed by the input filter”
– sub-section “Port timing”: changed symbol “t_pv” to “t_v(Q)”
– sub-section “Port timing”: changed symbol “t_ps” to “t_su(D)”
– sub-section “Port timing”: changed symbol “t_ph” to “t_h(D)”
– sub-section “Power-up timing”: changed symbol “t_PUR” to “t_pu(R)”
– sub-section “Power-up timing”: changed symbol “t_PUW” to “t_pu(W)”
– sub-section “Write cycle limits”: changed symbol “t_WR” to “T_cy(W)”
• Figure 23 “Write cycle timing”: changed symbol “t_WR” to “T_cy(W)”
• added Section 15 “Abbreviations”
