SN74LVC07AD

Introduction

The SN74LVC07AD is a 4-bit buffer/transceiver featuring non-inverting 3-STATE buffers and both direction 3-STATE transceivers. This integrated circuit was purpose built to provide a wide range of applications in embedded logic, industrial and automotive industries. Additionally, the SN74LVC07AD is capable of being completely powered down when it is not in use, making it one of the more desirable buffers available on the market.

Applications

The SN74LVC07AD is widely used in a variety of applications because of its versatility, low noise input thresholds, and high speed operation. Some of the more common applications include logic signals, memory decoding, data conversion, data multiplexing and demultiplexing, and as a level shifter. The SN74LVC07AD is also ideal for driving TTL loads with 3.3V supply

Technical Specifications

The SN74LVC07AD has a 4-bit configuration, with 4 non-inverting 3-STATE buffers and 4 dual direction 3-STATE transceivers. It can operate on a supply voltage of 1.65V to 3.6V and has an output voltage (low) of 0.4V. It has very fast switching time of 11ns (at 3.3V supply) and an input low to output low voltage of 0.1V. It has a max output current of +/-30mA and a typical quiescent current of 5µA.

Working Principle

The SN74LVC07AD contains 8-pins, they are 4 non-inverting inputs, 4 inverting inputs, 2 non-inverting outputs, and 2 inverting outputs. When the input passes low, the output goes high because of the buffer. When the input passes high, the output goes low because of the transceiver. Basically, the transceivers will switch the direction of the current depending on the state of the inputs. When both inputs are low, the outputs will be high and there will be no current flow. When both inputs are high, the outputs also will be high and again, no current flow.

Conclusion

The SN74LVC07AD is a versatile and reliable 4-bit buffer/transceiver featuring non-inverting 3-STATE buffers and both direction 3-STATE transceivers. It is suitable for a range of applications including logic signals, memory decoding, and level shifting. Additionally, the SN74LVC07AD is capable of being completely powered down when it is not in use, making it one of the more desirable and power efficient buffers available on the market.
