Key Features
- Octal 3-state buffer/driver with dual active-low output enable (OE1, OE2) for flexible bus control
- F/FAST logic family delivers high-speed switching performance with 50pF load capacitance support
- 64mA output sink current (I_OL) enables robust bus driving in high-fan-out applications
- DIP-20 package (R-PDIP-T20) for easy through-hole prototyping and legacy system compatibility
- Unidirectional signal flow simplifies board layout in data bus and address line buffering designs
Applications
The SN74F541N is widely used as a bus buffer and line driver in microprocessor and microcontroller systems, isolating address or data buses to prevent loading and signal degradation. It is suitable for memory interfacing, industrial control boards, and backplane driver applications where 3-state control and high output drive strength are required. Its dual enable inputs also make it ideal for multiplexed bus architectures and arbitrated data paths.

Frequently Asked Questions
What is the output drive capability of the SN74F541N?
The SN74F541N can sink up to 64mA (I_OL) per output, making it suitable for driving heavily loaded bus lines with a load capacitance of up to 50pF. This high sink current capability allows it to interface reliably with TTL and CMOS logic families in bus-oriented systems.
How does the dual output enable work on the SN74F541N?
The SN74F541N features two active-low output enable pins (OE1 and OE2). Both must be driven low simultaneously to enable the outputs; if either is high, all eight outputs enter the high-impedance (3-state) condition. This allows fine-grained bus control and easy expansion in multi-driver bus configurations.
What are common applications for the SN74F541N?
Common applications include address bus buffering in microprocessor systems, data line driving on backplanes, memory bank selection circuits, and industrial I/O expansion boards. Its 3-state outputs and strong drive current make it ideal anywhere multiple devices share a common bus.
What package does the SN74F541N come in and is it RoHS compliant?
The SN74F541N is available in a 20-pin Dual-In-Line Package (PDIP, JESD-30 code R-PDIP-T20). The JESD-609 code e4 indicates it meets RoHS compliant lead-free soldering requirements, making it suitable for modern eco-conscious designs.
