SN74LVC8T245DGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC8T245DGVR is an eight-bit non-inverting bus transceiver featuring configurable dual power supply rails for bidirectional voltage level translation. It supports VCCA and VCCB ranges from 1.65V to 5.5V, enabling universal translation between 1.8V, 2.5V, 3.3V, and 5V nodes. The device includes a direction-control (DIR) input and output-enable (OE) input to manage data flow between ports A and B. It offers robust glitch-free power sequencing and Ioff support for partial-power-down modes.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Fully configurable dual-rail design allows each port to operate over the full 1.65V to 5.5V power-supply range
• Robust, glitch-free power supply sequencing ensures safe operation during power transitions
• Ioff circuitry supports partial-power-down mode by disabling outputs to prevent damaging current backflow
• VCC isolation feature disables all I/O outputs when either VCC input is below 100mV or left floating

Buffers, Drivers, Receivers, Transceivers Applications

• Personal electronics: sound bar, flat-panel monitor
• Industrial: PLC controller, CNC controller, ultrasound scanner
• Computing: network attached storage
• Telecom: data center switch, baseband unit

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix 'DGVR' corresponds to the TVSOP-24 package with reel packaging. Confirm the specific revision level matches system requirements. Ensure ESD handling procedures are followed as the device exceeds JESD 22 HBM and CDM ratings. Check that unused inputs are tied to valid logic levels to minimize power consumption.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing systems operating at different interface voltages within the 1.65V to 5.5V range. It is suitable for asynchronous communication between two data buses. Consider the TVSOP-24 package constraints for board layout. Ensure control pins DIR and OE are supplied by VCCA.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC8T245 family of 8-bit dual-supply bus transceivers. The 'DGVR' suffix indicates a TVSOP-24 package variant manufactured by Texas Instruments. It shares core functionality with other package options like DB, PW, and RHL but differs in physical dimensions and thermal characteristics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include SN74LVC8T245DB, SN74LVC8T245PW, and SN74LVC8T245RHL. Verify pin compatibility and package dimensions before substitution. Ensure the replacement part meets the same voltage and thermal specifications.
