74ACT541TTR

Buffers, Drivers, Receivers, Transceivers Overview

The 74ACT541TTR is an octal bus buffer with 3-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. It provides high ESD immunity of 2KV and includes protection circuits against static discharge and transient excess voltage.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bus buffer design with non-inverted logic functionality

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 the specific ordering code suffix matches the required package type, as the TTR suffix indicates a TSSOP package in tape and reel format. Confirm that the application environment remains within the recommended operating temperature range of -55°C to 125°C and the supply voltage limits of 4.5V to 5.5V to ensure functional operation and prevent damage beyond absolute maximum ratings.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with 3-state outputs is required for high-speed CMOS applications interfacing with TTL levels. The flow-through architecture makes it suitable for microprocessor output ports where ease of layout and greater PC board density are priorities. Ensure the design accounts for the 50Ω transmission line driving capability and balanced propagation delays for signal integrity.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the advanced high-speed CMOS 74ACT series, which is compatible with standard 74 Series 541 pinouts and functions. It utilizes double-layer metal wiring C2MOS technology to achieve low power dissipation and high speed performance. The device is designed to directly interface various logic families, offering improved latch-up immunity compared to earlier generations.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AC541 serves as a non-inverting option within the same family but may differ in speed and voltage compatibility. Devices like the 74AC244 offer similar functionality but utilize a different pinout architecture (inputs and outputs on the same side), requiring PCB redesign if used as a direct replacement.
