Note 1: The absolute maximum ratings are rated values which must not be exceeded during operation, even for an instant. Any one of the ratings must not be exceeded. If any absolute maximum rating is exceeded, a device may break down or its performance may be degraded, causing it to catch fire or explode resulting in injury to the user. Thus, when designing products which include this device, ensurethat no absolute maximum rating value will ever be exceeded.
Note 2: Power Dissipation (PD); For PD, it is necessary to decrease 14.3 mw/°C.
DescriptionThe TMP88CU74 are the high speed and high performance 8-bit single chip microcomputers. These MCU contain 8-bit AD conversion inputs and a VFT (Vacuum Fluorescent Tube) driver on a chip.
