SN74LVC8T245DGVRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC8T245DGVRG4 is an eight-bit non-inverting bus transceiver with configurable dual power supply rails enabling bidirectional voltage level translation. It operates over a full 1.65V to 5.5V range on both VCCA and VCCB ports. The device features three-state outputs, robust glitch-free power sequencing, and Ioff support for partial-power-down modes. It provides high drive capability with up to 32mA output current at 5V and includes VCC isolation features that disable outputs if either supply drops below 100mV.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable dual-rail design supporting independent 1.65V to 5.5V operation on A and B ports
• Glitch-free power supply sequencing allowing flexible power-on or power-off sequences
• Ioff circuitry prevents damaging backflow current during partial-power-down states
• VCC isolation feature disables all I/O outputs when either supply voltage falls below 100mV

Buffers, Drivers, Receivers, Transceivers Applications

• Personal electronics such as sound bars and flat-panel monitors
• Industrial controllers including PLCs and CNC systems
• Enterprise computing and network attached storage
• Telecom data center switches and baseband units

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific DGVR package variant against the datasheet mechanical dimensions. Confirm RoHS compliance status matches project requirements. Ensure ESD handling protocols are followed due to CMOS sensitivity. Validate thermal performance under maximum load conditions using junction-to-ambient resistance values provided in the specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring asynchronous communication between buses operating at different voltage levels within the 1.65V to 5.5V range. Consider the TVSOP-24 package for space-constrained designs. Evaluate the 32mA drive strength against load capacitance to ensure signal integrity. Verify control input logic levels align with the driving source referenced to VCCA.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC8T245 family of translating transceivers manufactured by Texas Instruments. The 'DGVR' suffix indicates a TVSOP-24 package with tape-and-reel packaging. The 'G4' suffix denotes lead-free construction compliant with environmental standards. It serves as a bridge for interfacing low-voltage logic with higher voltage peripherals.
