74AC541PC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74AC541PC is an octal buffer and line driver belonging to the AC logic series. It features true (non-inverting) outputs with three-state capability, allowing connection to bus lines without contention. The device utilizes a 20-pin Plastic Dual-In-Line (PDIP) package. It operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Flow-through architecture with inputs and outputs located on opposite sides of the package to facilitate microprocessor interface and printed circuit board layout density.
• Three-state outputs designed to drive bus lines effectively while minimizing power consumption through reduced ICC and IOZ currents.
• Non-inverting output polarity providing true signal transmission for memory, address, and clock driver applications.

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

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer designation, as ON Semiconductor acquired Fairchild's logic business. Confirm the package type matches the required DIP-20 form factor. Ensure the AC series specifications align with system voltage and speed requirements before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a non-inverting octal buffer with flow-through pinout is required for high-density PCB layouts. The AC series offers faster switching speeds compared to standard HC or HCT families. Verify that the three-state control signals are compatible with the system's logic levels.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AC logic family, known for high-speed CMOS performance. It is functionally similar to the 74AC244 but differs in pinout arrangement, placing inputs on one side and outputs on the other. This configuration is distinct from standard bidirectional transceivers.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include the 74ACT541 for TTL-compatible input requirements and the 74AC244 for similar functionality with different pinout orientation. Cross-reference datasheets to ensure package compatibility and electrical parameter alignment.
