74ACT541MTR

Buffers, Drivers, Receivers, Transceivers Overview

The STMicroelectronics 74ACT541MTR is an octal bus buffer with three-state outputs, fabricated using sub-micron silicon gate C2MOS technology. It operates within a supply voltage range of 4.5V to 5.5V and supports a typical propagation delay of 4ns at VCC = 5V. The device features symmetrical output impedance with minimum source/sink currents of 24mA and quiescent supply current of 4μA maximum at 25°C. Inputs are compatible with TTL levels (VIH min 2.0V, VIL max 0.8V), and the package includes ESD protection circuits providing 2kV immunity.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features flow-through architecture with inputs and outputs on opposite sides of the package for improved PC board layout density.
• Includes dual output enable inputs that function as two-input AND gates to control high-impedance states.
• Provides balanced propagation delays and 50Ω transmission line driving capability.

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

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix 'MTR' corresponds to the Tape & Reel packaging format in official documentation. Confirm the specific package type (SOP or TSSOP) matches the design requirements, as datasheets list multiple variants under the same base part number. Ensure environmental operating conditions align with the specified -55°C to +125°C range.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing High-Speed CMOS systems with TTL, NMOS, or CMOS output voltage levels. The non-inverting logic function and flow-through pinout make it suitable for microprocessor output ports where ease of layout is critical. Consider the 24mA drive strength for direct load driving applications.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ACT series of advanced high-speed CMOS logic functions. It is functionally similar to the 74AC244 but utilizes a different pinout arrangement. The 74ACT541 serves as the non-inverting counterpart to the 74ACT540 inverter family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for cross-reference compatibility with other manufacturers' 74ACT541 variants. Verify pin-to-pin equivalence if substituting with 74AC541 or 74HC541 families, noting differences in speed and voltage thresholds.
