The LSF Type translators utilize passive switches to level shift voltages, allowing the device to support both open drain and push pull interface signals. Board designers have the freedom to adjust the device behavior with external components to satisfy specific system needs. As a result, designing with the LSF Family requires additional attention due to specific biasing requirements, external RC component guidelines, and other design considerations.
This application note takes a deeper look into some of the most commonly asked questions regarding this device and serves as an extension to the existing app note regarding the operation of the LSF family devices. Please see Voltage Translation with the LSF Family for an introduction to how the LSF Family devices operate in example applications.
