Introduction

The N74F543DB,112 is a logic buffer, driver, receiver, transceiver device designed for applications in logic level translation and signal line buffering in networks, busses and point-to-point communication. It is a low voltage device that operates in the 2.0 to 5.0 V supply range and is capable of driving two logic loads at up to 20mA. This device also supports active pull-up and pull-down that enables signal line protection and power saving in off-load conditions.

Application Fields

The N74F543DB,112 is suitable for a wide range of applications where logic level translation and signal line buffering is required. It is especially well suited to applications in networking, busses and point-to-point communication, such as in the automotive, industrial, and consumer electronics markets; this device can be used for:

• Low voltage applications
• Digital signal and interface communication
• Logic level translation to protect against noise
• Data processing
• Mixed device logic output shortings

Working Principle

The N74F543DB,112 operates as a four channel, high/low side buffer. The device has two outputs that together with two sets of configuration pins allow four channels of buffering.The device has an active pull-up and pull-down feature that enables the user to select how individual outputs behave when in the off-load state. The active pull-up and pull-down enables users to achieve higher efficiency when requiring signal protection between logic levels.The device is configured using two control pins, ‘OE’ and ‘Direction’. The ‘OE’ input pin is used to enable/disable the device and the ‘Direction’ control pin is used to select the direction of the buffers. The four channels of the device can be individually configured to operate as high-side, low-side, and three-state buffers.The N74F543DB,112 supports two logic levels, the 2.0 and 5.0 V supply range. The logic high output voltage for the device is 2.0 - 2.2 V and the logic low voltage is 0.9 - 1.0 V.

Conclusion

The N74F543DB,112 is a high/low side, four channel buffer device suitable for applications in low voltage networks, busses, and point-to-point communication. It is designed to provide noise and signal line protection, to support active pull-up and pull-down, and to drive two logic loads at up to 20mA. The device is configured using two control pins, ‘OE’ and ‘Direction’, and it operates within the 2.0 to 5.0 V supply range.
