74ACTQ541PC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ541PC is an octal buffer and line driver utilizing FACT Quiet Series technology. It features non-inverting 3-STATE outputs with inputs and outputs located on opposite sides of the package for flow-through architecture. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to +85°C. It provides TTL compatible inputs and outputs capable of sourcing or sinking 24 mA. Propagation delay ranges from 2.0 ns to 7.5 ns at 5.0V, while maximum quiescent supply current is 40.0 µA.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering code matches the specific package type required, as the 74ACTQ541PC denotes the 20-Lead Plastic Dual-In-Line Package (PDIP). Confirm the presence of the 'PC' suffix in the part number to ensure correct physical dimensions and lead configuration. Check datasheet specifications for absolute maximum ratings to prevent damage during system design integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-density board layout is required due to its flow-through input/output arrangement. It is suitable for applications demanding low simultaneous switching noise and robust ESD immunity. Ensure the system operates within the specified 4.5V to 5.5V supply voltage range and consider the 24 mA output drive capability for load requirements.

Direct substitutes include other octal 3-STATE buffers with similar ACT logic families and PDIP-20 packaging. Verify pinout compatibility and electrical characteristics such as propagation delay and output current before substitution.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the OE1 and OE2 pins?

OE1 and OE2 are active-LOW 3-STATE Output Enable pins. When either pin is HIGH, the outputs enter a high-impedance state.

How does the FACT Quiet Series technology benefit this device?

It guarantees quiet output switching, reduced ICC and IOZ currents, and improved dynamic threshold performance through GTO output control and undershoot correction.
