The SN74LVC138APWR is a 3-to-8 line decoder/demultiplexer logic circuit, often referred to as a decoder/demux. It belongs to the family of 74LVC logic chips, family of low power/low voltage circuit devices manufactured by Texas Instruments.The SN74LVC138APWR is mainly used for data communication and data switching applications. It can also be used in automotive, industrial and home applications. The SN74LVC138APWR can be used in applications where a compact and low power design is needed.The SN74LVC138APWR uses a 3-bit address for decoding up to 8 logic circuits (from A0 to A3) and one select signal (S). The output is low when S signal is high, otherwise the output circuits are disabled. Thus, the 8 outputs of SN74LVC138APWR can be used to drive up to 8 circuits with different reference voltages.The main feature of the SN74LVC138APWR is its low power consumption. It can draw only 10 µA at 3.3V supply voltage and 18.5 mA at 12V. This feature makes it suitable for portable applications and helps to reduce the system’s overall power consumption.The SN74LVC138APWR also offers a wide operating temperature range of -40° to 85°C and a high noise immunity with a CDM rating of 2kV. These features make it highly suitable for industrial and automotive applications.The SN74LVC138APWR can be mounted on the surface, the through-hole or the DIP version using switchable mounting pins. It can also be mounted vertically for space-critical applications.In summary, the SN74LVC138APWR is a versatile and low power device with a wide operating temperature range and high noise immunity. This makes it a suitable device for many data communication and data switching applications.
