UM809/810
Electrical Characteristics (Continued)
V_CC = full range, T_A = -40°C to +105°C (SOT23) or T_A = -40°C to +125°C (SC70), unless
otherwise noted. Typical values are at T_A =+25°C, V_CC = 5V for L/M/J versions, V_CC = 3.3V for
T/S versions, V_CC = 3V for R version, and V_CC = 2.5V for Z version. (Note 1)
