SN74LVCH8T245DGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH8T245DGVR is an 8-bit dual-supply bus transceiver from the Texas Instruments LVC family, housed in a 24-pin TVSOP package. It supports configurable voltage translation between A and B ports with independent VCCA (1.65V to 3.6V) and VCCB (1.65V to 5.5V) supplies. The device features non-inverting logic, tri-state outputs, and bidirectional data transfer controlled by DIR and OE inputs. It operates within a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable voltage translation allows independent supply voltages for each port
• Bidirectional data transfer capability between two distinct buses
• Tri-state outputs enable easy bus line driving without external buffers

Buffers, Drivers, Receivers, Transceivers Applications

• Mobile applications requiring low-voltage operation
• High-density memory card interfaces
• Point-to-point routing between different voltage domains

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'H' in the part number SN74LVCH8T245DGVR against official Texas Instruments documentation. The provided knowledge base contains data for SN74LVC8T245DGVR but lacks explicit confirmation that the 'H' variant shares identical electrical characteristics or pinout. Confirm RoHS compliance and package dimensions directly from the manufacturer's datasheet before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing systems with mismatched supply voltages, such as connecting a 1.8V processor to a 3.3V peripheral. Ensure the required propagation delay and output drive current meet the system timing specifications. Verify that the TVSOP-24 package fits the available PCB footprint and thermal constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVC8T245 family of level translators. It serves as a bridge for asynchronous communication between buses operating at different logic levels. The LVC series is optimized for low-power CMOS technology, providing high noise immunity while maintaining low static power consumption across the specified operating voltage range.
