SN74AVC20T245ZQLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC20T245ZQLR is a 20-bit dual-supply bus transceiver from the Texas Instruments AVC series, designed for configurable voltage translation between two independent power rails. It features bidirectional data flow control via a single direction pin and three-state outputs to isolate the device when disabled. The component operates within a supply voltage range of 1.2 V to 3.6 V on both ports A and B, supporting data rates up to 380 Mb/s. It is housed in a 56-pin Microstar Junior BGA package with dimensions of 6x10 mm and an operational temperature range of -40°C to +85°C.

• High-speed memory interface translation
• Portable equipment interconnects
• Consumer electronics level shifting

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix ZQLR corresponds to the Microstar Junior package variant. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure ESD handling protocols are followed due to the sensitive nature of CMOS logic inputs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing systems requiring 20-bit wide data paths with mixed voltage levels. Compare against the SN74AVC16T245ZQLR if fewer bits are sufficient. Consider the TVSOP-56 package option (SN74AVC20T245DGVR) if surface-mount BGA assembly capabilities are unavailable.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AVC20T245 family of dual-supply bus transceivers. It shares functional similarities with other members like the SN74AVC16T245 but offers higher pin density. The AVC series is optimized for low power consumption and high-speed performance in portable applications.
