Overview
The MC74ACT541ML1 is an octal buffer and line driver from onsemi's 74ACT logic series, housed in a 20-lead ML1 (SSOP) package. It features eight non-inverting channels with three-state outputs, operating within a 4.5V to 5.5V supply voltage range. The device provides symmetrical output drive currents of 24mA for both high and low states, ensuring robust signal integrity. Typical propagation delay is specified at 7.5ns at 5V, supporting high-speed digital applications. It functions within an industrial temperature range of -40°C to +85°C.
Feature Summary
- Three-state outputs enable bus sharing by isolating the device when not selected
- TTL-compatible inputs allow direct interfacing with standard TTL logic circuits
- High drive capability supports multiple loads without external buffering
Applications
- Memory address drivers
- Clock distribution networks
- Bus-oriented transceivers
Procurement Notes
Verify the specific suffix 'ML1' corresponds to the SSOP-20 package variant during procurement. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly process specifications. Ensure the ordering part number matches the exact manufacturer designation to avoid pinout or electrical characteristic mismatches.
Selection Notes
Select this component when an octal non-inverting buffer with three-state control is required in a compact surface-mount form factor. The ACT series offers a balance of speed and power consumption suitable for general-purpose digital systems. Consider the ML1 package dimensions if board space is constrained compared to standard SOIC options.
Part Context
This device belongs to the 74ACT family, which provides performance comparable to 74AC logic but with TTL-compatible input thresholds. The MC74ACT541 variant specifically offers non-inverting logic, distinguishing it from the MC74ACT540 which provides inverting outputs. Both share similar electrical characteristics and packaging options within the same product line.
Replacement Considerations
The CD74ACT541M96 from Texas Instruments is documented as a similar replacement option. Verify pin compatibility and electrical parameters before substitution.
