The 74ACT541SC is an octal buffer/driver with 3state outputs in a 20pin SOIC package (SOIC20, 0.300' width). It provides eight noninverting buffers with a common outputenable control, enabling flexible buffering and busdriving in 5V CMOS/TTLcompatible circuits. Key benefits 8bit buffering: Increases fanout capability and protects driving devices while delivering clean, buffered signals to downstream devices. 3state outputs: Enables tristate operation for shared buses and flexible system design; easily isolate or enable the bus as needed. Polarity: Noninverting buffers preserve original signal logic, reducing risk of polarity errors in digital designs. Compact packaging: SOIC20 package with 0.300' body width provides a compact, surfacemount solution suitable for dense PCBs. Compatible with standard logic levels: Suitable for 5V CMOS/TTLcompatible interfaces, enabling straightforward integration with common microcontrollers, memory, and peripherals. Fast CMOS ACT performance: Part of the ACT family, offering speed operation with low power consumption for modern digital designs. Singleunit packaging: Available as a single 74ACT541SC device, ready for inclusion in prototyping or production boards. Key attributes Model and package: 74ACT541SC, SOIC20300mil (20pin smalloutline package, 0.300' wide). Function: Octal buffer/driver with 3state outputs; eight noninverting buffers with a common output enable. Inputs/outputs: A inputs drive corresponding Y outputs; 8 channels. Output enable: Shared OE control enables or disables all eight outputs. Power: Designed for 5V CMOS logic; compatible with standard 4.5V–5.5V supply ranges (typical for ACT devices). Construction: Plastic surfacemount package suitable for automated assembly. Application footprint: Ideal for both production designs and development/testing environments requiring reliable 8bit buffering. Performance considerations Provides speed buffering with low input/output distortion for clean logic levels. Threestate outputs facilitate multidevice bus sharing without signal contention. Suitable for isolating loadcapacitance and protecting driving sources in mixedsignal or digitalheavy designs. Recommended use cases and applications Microcontroller data bus buffering: Use the 74ACT541SC to buffer an 8bit data bus between a microcontroller and peripherals, reducing loading on the MCU and protecting the controller from downstream signal characteristics. Memory and peripheral interfaces: Buffer address and control lines between a processor or controller and external memory or peripheral devices, with the ability to tristate the bus during reset or other bussharing scenarios. Development and prototyping: Implement an 8bit buffering stage on development boards to test signal integrity, fanout, and bus timing before committing to a final PCB design. Notes Ensure supply voltage within the device's specified range (typically 4.5V–5.5V) and observe proper decoupling close to the device. Verify OE control logic to guarantee correct enable/disable behavior in your circuit. 1 piece per unit This listing corresponds to a single 74ACT541SC part in an SOIC20300mil package.
