What is CD74ACT540M96G4 used for?
The CD74ACT540M96G4 octal inverting bus driver is widely used in microprocessor and microcontroller systems to buffer and drive data, address, and control buses between ICs at different drive strengths, enabling reliable communication across PCB traces with high capacitive loading. Its dual output enable inputs allow it to function as a bus isolator, selectively connecting or disconnecting bus segments in memory expansion, peripheral interface, and backplane applications. The ACT family's TTL-compatible inputs make it ideal for mixed 3.3V/5V systems and legacy-compatible designs requiring high fan-out with active bus drive.

Frequently Asked Questions
What is the logic family of the CD74ACT540M96G4 and what does it mean?
The CD74ACT540M96G4 belongs to the ACT (Advanced CMOS TTL-compatible) logic family. ACT devices feature CMOS technology with TTL-compatible input thresholds, enabling them to interface directly with TTL outputs while consuming much less power than equivalent TTL devices. The ACT family offers high noise immunity and is suitable for systems requiring 5V operation with TTL input compatibility.
What is the output drive current of the CD74ACT540M96G4?
The CD74ACT540M96G4 provides a maximum output low current (IOL) of 24mA (0.024A) per output channel. This high drive capability allows it to sink significant current when driving heavily loaded bus lines with 50pF load capacitance. The 8 parallel output channels enable simultaneous driving of an 8-bit data or address bus with strong fan-out capability.
How does the output enable work on the CD74ACT540M96G4?
The CD74ACT540M96G4 features dual output enable inputs, both active-low (Control Type: Enable Low). When either enable input is high, all 8 outputs are placed in the high-impedance (tri-state) condition, isolating the bus. Both enable inputs must be asserted low simultaneously to activate the outputs, providing flexibility for various bus control and gating configurations.
What package does the CD74ACT540M96G4 come in?
The CD74ACT540M96G4 is packaged in an R-PDSO-G20 (20-pin plastic dual small outline), commonly known as a 20-pin SOIC. The M96 suffix indicates the 96-unit tape-and-reel format for automated SMT assembly. The G4 suffix confirms RoHS-compliant lead-free construction (JESD-609 code e4), meeting current environmental standards.
What are common applications for the CD74ACT540M96G4?
Common applications include driving data and address buses in microprocessor systems, acting as bus buffers between CPUs and memory or peripheral devices, bus isolation and direction control in backplane designs, signal level restoration on long PCB traces, and interface buffering between logic families. The inverting characteristic makes it suitable for applications requiring complementary bus drive or signal inversion.
