Key Features
- 8-bit unidirectional 3-state buffer drives up to 50 pF bus capacitance at ACT switching speeds for high-speed data bus applications
- Dual active-low output enable control pins allow flexible bus isolation and multiplexing without external gates
- 4.5 V to 5.5 V ACT-family supply range ensures TTL-compatible input thresholds and full CMOS output levels in 20-pin SOIC
Applications
The CD74ACT541M is used in microprocessor system buses, memory address and data bus drivers, and backplane interface circuits where non-inverting 3-state buffering of 8-bit parallel data is required at TTL-compatible levels. Its dual output enable inputs simplify bus arbitration logic in multi-master systems, reducing external gate count. The device also serves as an isolation buffer between different bus segments in industrial control systems and data acquisition cards operating from a 5 V supply.

Frequently Asked Questions
What supply voltage does the CD74ACT541M require and how many data bits does it buffer?
The CD74ACT541M operates from a 4.5 V to 5.5 V supply and provides 8 bits of unidirectional non-inverting 3-state buffering, supporting standard TTL input thresholds and enabling full CMOS output voltage swings across a 50 pF rated load capacitance.
How do the dual output enable pins on the CD74ACT541M simplify bus multiplexing in a multi-board system?
The device provides two independent active-low output enable inputs (OE1 and OE2); both must be asserted low to enable all 8 outputs simultaneously, which allows simple glue-free bus sharing between two bus masters without requiring additional AND or NOR gate logic in 5 V backplane designs.
Is the CD74ACT541M a suitable drop-in replacement for 74ACT541 devices from other vendors in existing SOIC-20 PCB layouts?
Yes; the CD74ACT541M is functionally and pin-compatible with standard 74ACT541 devices from other manufacturers, sharing the same 20-pin SOIC footprint with 1.27 mm lead pitch, identical logic function, and 4.5 V to 5.5 V operating range, making it a direct replacement in existing board layouts.
