74ACTQ18825MTDX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ18825MTDX is an 18-bit non-inverting buffer and line driver featuring 3-STATE outputs. It utilizes FACT Quiet Series technology to ensure quiet output switching and improved dynamic threshold performance. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of -40°C to +85°C. Each byte has separate 3-STATE control inputs, allowing for independent or combined operation. The component is housed in a 56-Lead Thin Shrink Small Outline Package (TSSOP).

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering code suffix 'X' corresponds to the Tape and Reel packaging variant when procuring. Confirm that the component meets the required environmental standards and package specifications for the intended application. Ensure compatibility with the 4.5V to 5.5V supply voltage range and the -40°C to +85°C operating temperature limits during system integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-density 18-bit buffering with independent byte control. The FACT Quiet Series technology makes it suitable for systems sensitive to simultaneous switching noise. Consider the 56-lead TSSOP package constraints and the 24 mA output drive capability when designing the circuit layout and load requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

The 74ACTQ18825 belongs to the ACTQ logic family, which combines AC speed with QUIET SERIES features. This series is designed to minimize noise emissions while maintaining fast propagation delays. The 18-bit configuration provides a specialized solution for wide bus applications where standard 8-bit or 16-bit buffers would require multiple devices.
