74ACT16646DLRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT16646DLRG4 is a 16-bit registered bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs with CMOS outputs. The device provides three-state outputs and includes internal registers that clock data from the A or B bus. It exhibits a propagation delay of 11.1 ns and supports low-level output currents of 24 mA and high-level output currents of -24 mA. Designed for surface-mount installation, it is housed in a 56-pin SSOP package and functions across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates compliance with RoHS directives and lead-free manufacturing standards as per Texas Instruments documentation. Confirm the package designation corresponds to the 56-lead SSOP form factor. Ensure the component matches the active status indicated in official product selection guides before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring simultaneous bus interfacing and data registration. The ACT series offers faster switching speeds compared to standard 74LS equivalents while maintaining compatible pinouts. Consider the 56-pin SSOP package constraints regarding PCB space and thermal dissipation requirements for dense layouts.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74ACT logic family, which utilizes advanced silicon-gate CMOS technology. The 74ACT16646 variant specifically addresses applications needing wide-width data handling with latching capabilities. It serves as a registered version of standard bus transceivers, allowing data synchronization at the receiving end.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74ACT16646DLR is the non-RoHS compliant equivalent of this component. Verify functional compatibility if substituting with other 16-bit registered transceivers from different manufacturers, ensuring voltage levels and pin configurations align.
