Application Notes
- Flexible Voltage-Level Translation With CBT Family DevicesPDF, 40 Kb, File published: Jul 20, 1999
Voltage translation between buses with incompatible logic levels can be accomplished using Texas Instruments (TI) translation-voltage clamps (TVC) or standard crossbar technology (CBT) devices. CBT devices in this application offer flexibility in designs, protection of circuits that are sensitive to high-state voltage-level overshoots, and cost efficiency. - 5-V To 3.3-V Translation With the SN74CBTD3384 (Rev. B)PDF, 35 Kb, Revision: B, File published: Mar 1, 1997
The emergence of low-voltage technology required existing 5-V systems to interact with 3.3-V systems. Compatibility issues of mixed-mode operation created the need for 5-V to 3.3-V translation. Buffers and transceivers serve as effective translators. While providing additional drive, these devices also add propagation delay and require directional control. In cases where additional drive is not - 3.3-V to 2.5-V Translation with Texas Instruments Crossbar Technology (Rev. A)PDF, 32 Kb, Revision: A, File published: Apr 3, 1998

- Bus FET Switch Solutions for Live Insertion ApplicationsPDF, 300 Kb, File published: Feb 7, 2003
In today?s competitive computing and networking industry, any equipment downtime due to component interconnects or bus failures impedes communication, hinders productivity and hampers financial growth. In recognizing this increasingly costly unplanned downtime, the industry introduced live-insertion technology to minimize the impact of any such failures. The live-insertion feature enables a networ
