Architecture The TXB0108 architecture (see Figure 1) does not require a direction-control signal to control the direction of data flow from A to B or from B to A. In a dc state, the output drivers of the TXB0108 can maintain a high or low, but are designed to be weak, so that they can be overdriven by an external driver when data on the bus starts flowing the opposite direction. The output one shots detect rising or falling edges on the A or B ports. During a rising edge, the one shot turns on the PMOS transistors (T1, T3) for a short duration, which speeds up the low-to-high transition. Similarly, during a falling edge, the one shot turns on the NMOS transistors (T2, T4) for a short duration, which speeds up the high-to-low transition. The typical output impedance during output transition is 70 Ω at VCCO = 1.2 V to 1.8 V, 50 Ω at VCCO = 1.8 V to 3.3 V and 40Ω at VCCO = 3.3 V to 5 V. Figure 1. Architecture of TXB0108 I/O Cell Input Driver Requirements Typical IIN vs VIN characteristics of the TXB0108 are shown in Figure 2. For proper operation, the device driving the data I/Os of the TXB0108 must have drive strength of at least ±2 mA. 10 Submit Documentation Feedback Copyright © 2006–2010, Texas Instruments Incorporated Product Folder Link(s): TXB0108 |
