SN74ALVCH16525DGGR

Overview

The SN74ALVCH16525DGGR is an 18-bit universal bus transceiver from Texas Instruments, housed in a 56-pin TSSOP package. It operates on a single supply voltage ranging from 1.65 V to 3.6 V. The device features non-inverting logic with three-state outputs capable of sourcing -24 mA and sinking 24 mA. Quiescent current is typically 40 µA. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports bidirectional data transmission across 18 bits
• Enables level translation between different voltage domains
• Provides high drive capability for system interconnects

Applications

• High-density data buses
• Memory interface circuits
• Portable computing systems

Procurement Notes

Verify the specific suffix DGGR corresponds to the TSSOP-56 reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input voltage levels remain within the specified 1.65 V to 3.6 V operational range to prevent device damage or functional failure during operation.

Selection Notes

Select this component when an 18-bit wide bus interface is required with low-voltage compatibility. The ALVCH series offers improved performance over standard LVCH variants. Verify that the 56-pin TSSOP footprint matches the target PCB layout constraints and thermal requirements for the intended application environment.

Part Context

This part belongs to the SN74ALVCH16xxx family of universal bus transceivers. These devices are designed for low-voltage applications requiring high-speed data transfer. The 18-bit width distinguishes it from 8-bit or 16-bit counterparts, making it suitable for wider data paths in compact form factors.

Replacement Considerations

Cross-reference with SN74ALVCH16825DGGR for similar 18-bit functionality. Verify pinout compatibility and electrical specifications before substitution. Ensure the alternative device supports the same voltage range and package type.
