SN74ALVTH162827GR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVTH162827GR is a 20-bit buffer and line driver manufactured by Texas Instruments, utilizing Advanced BiCMOS Technology (ABT). It operates at 2.5-V or 3.3-V VCC with TTL-compatible inputs supporting up to 5.5-V signals. The device features two independent 10-bit sections, each with separate output-enable controls. Outputs are 3-state with equivalent 30-Ω series resistors and sink up to 12 mA. Active bus-hold circuitry prevents floating inputs. It is housed in a 56-pin Thin Shrink Small-Outline (DGG) package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation with 5-V tolerant inputs for 2.3-V to 3.6-V VCC systems
• Active bus-hold circuitry eliminates the need for external pullup or pulldown resistors on data inputs
• Outputs include equivalent 30-Ω series resistors to minimize overshoot and undershoot without external components
• Auto3-State functionality prevents driver conflict during power-up and power-down sequences

Buffers, Drivers, Receivers, Transceivers Applications

• High-density data buffering in 2.5-V and 3.3-V memory architectures
• Clock distribution and buffering in mixed-voltage system environments
• Bus drivers requiring live insertion capabilities with high-impedance states

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors as this part may be obsolete. Confirm package marking matches the DGG designation. Ensure supply chain sources provide valid traceability documentation. Check RoHS compliance status against current environmental regulations before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 5-V logic with lower voltage buses. The dual 10-bit architecture allows flexible control of data flow. Verify that the 12-mA output drive capability meets load requirements. Consider thermal performance within the TSSOP-56 package for high-speed switching applications.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the ALVTH family designed for low-power operation with high-speed performance. It complements other widebus buffers by providing 20-bit capacity in a single package. The ABT technology ensures low static power dissipation while maintaining fast propagation delays suitable for modern digital systems.
