ON Semiconductor MC74VHCT541ADT Octal Bus Buffer

The MC74VHCT541ADT is a high-performance octal bus buffer from ON Semiconductor, designed to provide a seamless interface between two buses in a digital circuit. This integrated circuit is part of the high-speed CMOS family and is particularly well-suited for driving bus lines or buffer memory address registers owing to its robust output drivers and high current sinking capability.

Constructed with silicon gate CMOS technology, it has the advantage of high speed operation similar to LSTTL combined with the low power consumption of standard CMOS integrated circuits. This makes the MC74VHCT541ADT an excellent choice for systems that require high-speed data transfer while maintaining energy efficiency.

Key Features:

• Logic Type: Octal Bus Buffer
• Number of Channels: 8
• Output Type: 3-State
• High Output Current: -32mA / 64mA
• Supply Voltage Range: 4.5V to 5.5V
• Propagation Delay Time: 8.5ns at 5V
• Operating Temperature Range: -55°C to 125°C
• Mounting Type: Surface Mount
• Package / Case: TSSOP-20
• Compliance: Lead-Free / RoHS Compliant

The device features eight non-inverting buffers with 3-state outputs that can be placed in a high-impedance state effectively disconnecting the output from the bus. This feature is particularly useful in multiplexed bus applications where data integrity is critical, as it prevents data contention and ensures that only one device drives the bus at any given time.

The MC74VHCT541ADT operates over a broad voltage range and provides guaranteed performance over the full temperature range of -55°C to 125°C. Its fast propagation delay and transition times make it ideal for interfacing with high-speed microprocessors and can significantly improve the performance of a system.

With its industry-standard TSSOP-20 package, the MC74VHCT541ADT is easy to integrate into a wide variety of designs. The device is also lead-free and RoHS compliant, ensuring that it meets current environmental standards for electronic components.

Whether you're designing data communication systems, memory buffer interfaces, or input/output port expansions, the ON Semiconductor MC74VHCT541ADT offers a reliable and efficient solution for your buffering needs.
