Note: *V_IHmin = V_CC –1.0 V, V_ILmax = 0.8 V (all output terminals are at no load); V_CC = 5.0 V.
**V_CC = 5 V + 10%, V_SS = 0 V over specified temperature range, unless otherwise noted
AC Characteristics
Table 7, Table 8, and Table 9 provide AC characteristics for the
Z80180-6, Z80180-8, and Z80180-10, respectively.
V_CC = 5 V + 10%,
V_SS = 0 V, TA – 0 °C to +70 °C, unless otherwise noted.
