Notes: 1. This figure omits the test circuits and pin numbers 2, 3, 4, 9, 10, 12, and 14 for the user connector that are
not used when H8/Tiny or H8/Super Low Power series is connected.
2. The power of 74LVC125B is supplied from Vcc in the user connector (or in the power-supply circuit during
power-supply mode).
