    Products Detail

    M74HC540B1R Overview


    There is a neat 20-DIP (0.300, 7.62mm) package used in buffer. A Tube external packaging is used for this buffer. The external packaging used in this logic IC is the Through Hole external packaging. This is a typical Buffer, Inverting logic integrated circuit with a wide range of applications. There's a 2V~6V supply voltage for this logic IC. This automotive buffer is capable of working through -55°C~125°C TA. This buffer IC has a 7.8mA 7.8mA high and low logic state output current. There are 3-State outputs that digital buffer can handle. A total of 1 elements are used. 74HC series devices are included in this network transceiver. 20 terminations with different functions are available on this transceiver. An input voltage of 4.5V is required. HC/UH family part. With the electrical part, 20 pins are set. Through Hole applications are suitable for it. There are 20 pins on digital buffer. The bus transceiver has 2 ports. For other related electronic components, you can search M74HC54. In particular, automotive buffer is a type of Bus Driver/Transceivers. When the electronic component is quiescent, it uses 4?A. Power supplies with a 2/6V volt rating are recommended. The digital buffer requires a minimum voltage of 2V. 8 efficient bits are included in the package of the network transceiver. For better service, buffer includes WITH DUAL OUTPUT ENABLE. The logical driver has the ability to output 3 signal lines at the same time. Signal transmission is more cost-effective with its 8 lines level input capability. ENABLE LOW control technology allows the logical driver to start up.
