HD64F3437TF16 Datasheet, PDF (609/752 Pages) Hitachi Semiconductor – 12 V must not be applied to the S-mask model (single-power-supply specification), as this may permanently damage the device.

23.4 Electrical Characteristics (H8/3437SF Low-Voltage Version)
23.4.1 DC Characteristics
Table 23.17 lists the DC characteristics. Table 23.18 gives the allowable current output values.
Bus drive characteristics common listed in table 23.19.
Table 23.17 DC Characteristics
Conditions: V_CC = 3.0 V to 5.5 V, V_CCB = 3.0 V to 5.5 V, AV_CC = 3.0 V to 5.5 V^*1,
AV_ref = 3.0 V to AV_CC, V_SS = AV_SS = 0 V, Ta = –20˚C to +75˚C (regular
specifications), Ta = –40°C to +85°C (wide-range specifications)
