SN74ALVCH16825DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH16825DLR is an 18-bit buffer and line driver with 3-state outputs, designed for 1.65-V to 3.6-V VCC operation. It features active bus-hold circuitry on data inputs to maintain valid logic levels without external pullup or pulldown resistors. The device supports two 9-bit buffers or one 18-bit buffer configuration. It utilizes Texas Instruments' EPIC submicron process and provides ESD protection exceeding 2000 V per MIL-STD-883. Characterized for operation from -40 °C to 85 °C, it improves performance and density in memory address drivers, clock drivers, and bus-oriented receivers.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• ESD protection exceeds 2000 V per MIL-STD-883 Method 3015
• Latch-up performance exceeds 250 mA per JESD 17

Buffers, Drivers, Receivers, Transceivers Applications

• 3-state memory address drivers
• Clock drivers
• Bus-oriented receivers and transmitters

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant (DL or DGG) against the required footprint, as both are available under the same base part number. Confirm RoHS compliance and moisture sensitivity level ratings prior to assembly. Ensure supply chain sources provide original manufacturer documentation to validate authenticity and production status.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring wide voltage compatibility between 1.65 V and 3.6 V. The integrated bus-hold feature simplifies board layout by removing external resistor requirements. Consider the 56-pin SSOP or TSSOP package options based on available PCB space and thermal management needs.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments Widebus family and is manufactured using the EPIC Enhanced-Performance Implanted CMOS submicron process. It is designed to enhance system density and performance compared to standard logic families. The DL suffix indicates a plastic shrink small-outline package.
