What are the key features of CD74ACT541EE4?

  • 8-channel non-inverting tri-state outputs allow clean bus sharing and high-impedance release in multi-driver systems
  • ACT logic family provides fast CMOS-speed switching with TTL-compatible input thresholds at 5V
  • Dual active-low output enable controls enable flexible bus arbitration and master/slave bus architectures
  • Through-hole 20-pin PDIP package simplifies prototyping, hand-assembly, and legacy board replacement

What is CD74ACT541EE4 used for?

The CD74ACT541EE4 is widely used for buffering 8-bit data buses in microprocessor development boards, FPGA evaluation kits, and educational electronics platforms where through-hole assembly is preferred. Its tri-state outputs and dual enable pins make it suitable for bus isolation and direction control between different logic voltage domains or multiple bus masters. The device also serves as a direct replacement in legacy industrial control systems and test equipment that originally used 74ACT or 74HCT541 bus drivers.

Frequently Asked Questions

What is the difference between the CD74ACT541 and CD74HCT541?

Both are 8-bit non-inverting bus drivers with tri-state outputs, but the ACT family (CD74ACT541) uses TTL-compatible input thresholds (VIH min 2V), while the HCT family also accepts TTL levels. The ACT family generally offers faster propagation delays and higher output drive strength, making it preferred in high-speed backplane or memory bus applications where signal integrity is critical.

How do the dual output enables work on the CD74ACT541EE4?

The CD74ACT541EE4 has two active-low output enable pins (OE1 and OE2). Both must be pulled low to enable all eight outputs simultaneously. If either enable pin goes high, all outputs enter a high-impedance tri-state mode, disconnecting the driver from the bus and preventing bus contention in multi-master systems.

What load capacitance can the CD74ACT541EE4 drive?

The CD74ACT541EE4 is specified for a maximum load capacitance of 50pF per output. This is sufficient for most PCB traces in embedded processor, FPGA, and microcontroller bus applications. Exceeding this capacitance will increase propagation delay, so decoupling and series resistors may be needed for longer or heavily loaded bus segments.

Is the CD74ACT541EE4 RoHS compliant?

Yes, the CD74ACT541EE4 is lead-free and RoHS compliant as indicated by its 'e4' JESD-609 code and the Pb-free designation. This makes it suitable for environmentally compliant manufacturing in compliance with European RoHS directives and global green electronics regulations.

What package does the CD74ACT541EE4 use?

The CD74ACT541EE4 is housed in a 20-pin PDIP (Plastic Dual In-line Package) through-hole package. PDIP is ideal for prototyping, breadboard testing, and hand-soldering in educational or low-volume production environments, and the 20-pin format is compatible with standard IC sockets.
