Dual supply translating transceiver; open drain; auto direction sensing
During an input transition, a one-shot accelerates the output transition by switching on the
PMOS transistors (T1, T3) for a LOW-to-HIGH transition. Alternatively, it switches on the
NMOS transistors (T2, T4) for a HIGH-to-LOW transition. Once activated, the one-shot is
de-activated after approximately 25 ns (see Figure 11
). During the acceleration time, the
driver output resistance is between approximately 10 and 35 . To avoid signal
contention, the application must not exceed the maximum data rate or wait for the
one-shot circuit to turn-off, before applying a signal in the opposite direction.
