MM74HC541SJ Application Field and Working Principle

Logic - Buffers, Drivers, Receivers, TransceiversThe MM74HC541SJ is a high-speed CMOS 3-state non-inverting buffer made with advanced complimentary metal-oxide semiconductor (CMOS) technology. The MM74HC541SJ is designed to provide high speed data and clock synchronizing, bus driving capability and enhanced noise margin. It can be used for buffering address and data for memory decoders, clock drivers and other applications that require low pin count buffering.

Application Field

The MM74HC541SJ can be used in a variety of applications including buffering of communication and networking standard interfaces, such as USB, Ethernet, Coax, Wi-Fi, etc., as well as in computing and peripheral applications. It can also be used in audio and video buffering applications.

Working Principle

The MM74HC541SJ contains two independent buffer stages. Each buffer operates as a three-state non-inverting buffer, i.e., the outputs are high impedance when the Input Enable signal is low. The input signals applied to both the sections, can be either either 1 (logic high) or 0 (logic low) independent of the clock signal.The output of both the buffer stages is enabled/disabled by driving the Input Enable (INV) input signal low/high. The upper-order buffer is enabled when the INV signal is low, while the lower-order buffer is enabled when the INV signal is high. Both the inputs and outputs are capable of driving up to 15 ma loads and source up to 8 ma current. The propagation delay of the MM74HC541SJ is typically 15 ns, while the power dissipation is 95 mW.

Conclusion

The MM74HC541SJ is a high-speed CMOS 3-state non-inverting buffer intended for use in buffering address and data for memory decoders, clock drivers and other applications that require low pin count buffering. This buffer can be used in a variety of applications including buffering of communication and networking standard interfaces, such as USB, Ethernet, Coax, Wi-Fi, etc., as well as in computing and peripheral applications. It also offers excellent noise margin and low power dissipation.
