tolerant on input pins onlyâ; added Footnote 1.
⢠Figure 9 âAutoflow control (auto-RTS and auto-CTS) exampleâ updated
⢠Table 24 âLimiting valuesâ:
â parameter description for symbol Vn changed from âvoltage at any pinâ to âvoltage on any
other pinâ; added separate conditions for âat D7 to D0â and âat any input only pinâ
â symbol for âtotal power dissipation per packageâ changed from âPtot(pack)â to âPtot/packâ
⢠Table 25 âStatic characteristicsâ:
â symbol âVIL(CK)â changed to âVIL(clk)â
â symbol âVIH(CK)â changed to âVIH(clk)â
â parameter description for VOL: moved âon all outputsâ to Conditions column
â symbol/parameter âICL, clock leakageâ changed to âIL(clk), clock leakage currentâ
â deleted (empty) Typ columns
⢠Table 26 âDynamic characteristicsâ:
â symbol ât1w, t2w, clock pulse durationâ is split to two symbols/parameters: âtWH, pulse
width HIGHâ and âtWL, pulse width LOWâ
â Table note [2]: fractionâs denominator changed from ât3wâ to âtw(clk)â
â added Table note [4] and its reference at tRESET
⢠Figure 23 âExternal clock timingâ:
â symbol changed from ât2wâ to âtWLâ
â symbol changed from ât1wâ to âtWHâ
â symbol changed from ât3wâ to âtw(clk)â
⢠updated soldering information
