Key Features
- Octal 3-state non-inverting buffer with dual active-low output enable for flexible bus control
- ACT-family logic ensures TTL-compatible inputs and CMOS-level outputs for mixed-logic interfacing
- 20-pin DIP package rated at 50 pF load capacitance, suitable for breadboard prototyping and through-hole PCBs
Applications
The CD74ACT541E is widely used as a bus buffer and line driver in microprocessor memory interfaces, where its 8-channel 3-state outputs allow multiple devices to share a common data bus without contention. Its dual output-enable control also makes it effective in bidirectional bus arbitration logic and address latching circuits in industrial embedded systems.

Frequently Asked Questions
How does the dual output enable on CD74ACT541E help manage bus contention in a multi-master system?
The CD74ACT541E provides two independent active-low output enable pins, allowing the designer to AND-control bus access from two sources. When either enable is high, all 8 outputs enter high-impedance 3-state mode, preventing bus contention at 50 pF load capacitance per output.
Which supply voltage range does the CD74ACT541E operate on, and is it TTL-compatible?
The CD74ACT541E belongs to the ACT logic family and operates from a 5 V supply. Its inputs are TTL-compatible (VIH = 2 V min), allowing direct interfacing with both TTL and CMOS logic without level-shifting components in mixed-logic board designs.
What package does the CD74ACT541E use, and how does it compare to SOIC alternatives for prototyping?
The CD74ACT541E uses a 20-pin PDIP (through-hole DIP) package, which is ideal for breadboard prototyping. The SOIC surface-mount version offers a smaller footprint at the same 50 pF load rating for production PCBs where space is constrained.
When should a designer choose CD74ACT541E over a 74HC541 for a 5 V bus driver application?
CD74ACT541E is preferred when TTL-level input thresholds are required alongside CMOS output drive. The ACT family accepts inputs as low as 2 V as logic high, whereas HC family requires 3.5 V at 5 V supply, making ACT more robust in noisy 5 V bus environments with 8 channels.
