Architecture of NTB0101 I/O cell
13.2 Architecture
The architecture of the NTB0101 is shown in
extra input signal to control the direction of data flow from A to B or from B to A. In a static
state, the output drivers of the NTB0101 can maintain a defined output level, but the
output architecture is designed to be weak, so that they can be overdriven by an external
driver when data on the bus starts flowing in the opposite direction. The output of one-shot
circuits detect rising or falling edges on the A or B ports. During a rising edge, the
one-shot circuits turn on the PMOS transistors (T1, T3) for a short duration, accelerating
the LOW-to-HIGH transition. Similarly, during a falling edge, the one-shot circuits turn on
the NMOS transistors (T2, T4) for a short duration, accelerating the HIGH-to-LOW
transition. During output transitions the typical output impedance is 70  at V
to 1.8 V, 50  at V
