74ACTQ541MTCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ541MTCX is an octal buffer and line driver utilizing FACT Quiet Series technology. It features non-inverting 3-STATE outputs with inputs and outputs positioned on opposite sides of the package for flow-through architecture. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. It provides output source/sink currents of 24 mA, typical propagation delays of 2.0 ns at 5.0V, and guaranteed simultaneous switching noise performance.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• FACT Quiet Series technology ensures reduced ICC and IOZ by 50% alongside improved dynamic threshold performance.
• Flow-through pinout arrangement places inputs and outputs on opposite package sides to facilitate easy board layout and higher density.
• Outputs provide non-inverting 3-STATE functionality with guaranteed 4 kV minimum ESD immunity.
• Inputs are TTL compatible, allowing direct interfacing with standard logic families.

Buffers, Drivers, Receivers, Transceivers Applications

• Memory and address drivers
• Clock drivers
• Bus-oriented transmitter/receivers
• Microprocessor output ports

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering code includes the 'X' suffix to confirm tape and reel packaging availability. Confirm the specific package variant matches design requirements, as the base part number covers SOIC, TSSOP, and PDIP options. Ensure compatibility with the 4.5V to 5.5V supply voltage range and check for moisture sensitivity handling during storage and assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-density PCB layouts require flow-through signal paths between input and output pins. Choose the 74ACTQ541MTCX over standard variants if reduced simultaneous switching noise and lower quiescent current are critical system requirements. Verify that the 24 mA drive capability meets load specifications and that the 4.5V to 5.5V operating range aligns with the target power supply.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ACTQ541 family, which utilizes Fairchild's FACT Quiet Series technology. It functions similarly to the 74ACTQ244 but differs in providing a flow-through architecture rather than a buffered configuration. The series is designed for applications requiring superior noise performance and dynamic threshold stability compared to standard ACT logic devices.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the 74ACTQ541SC (SOIC) and 74ACTQ541PC (PDIP). For alternative packages, verify pinout compatibility with the 20-lead TSSOP or SOIC form factors. Cross-reference with other manufacturers' octal buffers ensuring matching 3-STATE control logic and voltage levels.
