7.3.1 Architecture

The TXS0204 architecture (see Figure 7-1) does not require a direction-control signal to control the direction of data flow from A to B or from B to A.

Each A-port I/O has an internal 10kΩ pullup resistor to VCCA, and each B-port I/O has an internal 10kΩ pullup resistor to VCCB. The output one-shots detect rising edges on the A or B ports. During a rising edge, the one-shot turns on the PMOS transistors (T1, T2) for a short duration which speeds up the low-to-high transition.
