74ACT16825DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT16825DLR is an 18-bit buffer and line driver from the Texas Instruments 74ACT logic family, housed in a 56-pin SSOP package. It features non-inverting inputs with three-state outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 9.6 ns at 5 V, high-level output current of -24 mA, and low-level output current of 24 mA. Static current is 8 µA, with a maximum power dissipation of 1.4 W. It functions across an industrial temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DLR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 56-lead SSOP footprint matches the target PCB design constraints. Ensure the 74ACT logic level compatibility aligns with the system's 5V operating environment before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-density 18-bit buffering is required within a single package. The ACT series offers speed comparable to LS TTL but with CMOS power efficiency. Consider the 56-pin SSOP form factor for space-constrained designs requiring surface-mount installation. Verify that the 24 mA drive capability meets the load requirements of the connected bus lines.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74ACT series, which bridges the performance gap between standard TTL and CMOS logic families. The 74ACT16825 specifically addresses the need for wide-word data handling in 5V digital systems. It serves as a fundamental building block for managing large parallel data transfers in microprocessor-based architectures.
