74ACT16827DLR

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments 74ACT16827DLR is a noninverting 20-bit buffer and driver featuring 3-state outputs. It utilizes the EPIC (Enhanced-Performance Implanted CMOS) process within the Widebus family, housed in a 56-pin SSOP package. The device operates on a supply voltage of 4.5 V to 5.5 V with an operating temperature range of -40°C to +85°C. Electrical characteristics include high-level output current of -24 mA and low-level output current of 24 mA. Propagation delays are specified at 9.8 ns maximum for both tPLH and tPHL transitions.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DLR' corresponds to the tape-and-reel packaging format containing 1000 units per reel. Confirm that the active status aligns with current design requirements. Ensure compatibility with standard lead-free soldering profiles as indicated by the RoHS compliance classification. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a high-density 20-bit buffer solution is required within a compact surface-mount footprint. The flow-through architecture facilitates efficient routing compared to traditional parallel architectures. Verify that the system logic levels match the TTL-compatible input specifications. Ensure the power supply remains stable within the 4.5 V to 5.5 V range to maintain signal integrity and proper 3-state operation across the industrial temperature spectrum.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ACT logic family, utilizing EPIC technology for enhanced performance. It is part of the Widebus family, designed to provide double the I/O pin count of standard small-outline packages within the same PCB area. The DL package variant offers 25-mil center-to-center pin spacings, facilitating dense circuit board designs while maintaining robust electrical characteristics for high-speed digital applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ACT16827DL is the tube-packaged equivalent of the DLR variant. Both share identical electrical specifications and functionality. Verify that the chosen replacement matches the required packaging quantity and handling method for the assembly line.
