SN74LVC8T245PWRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC8T245PWRG4 is an eight-bit non-inverting bus transceiver with configurable dual power supply rails enabling bidirectional voltage level translation. It operates with VCCA and VCCB set between 1.65V and 5.5V, supporting universal low-voltage translation between 1.8V, 2.5V, 3.3V, and 5V nodes. The device features three-state outputs controlled by DIR and OE inputs referenced to VCCA. It supports partial-power-down mode via Ioff circuitry and includes VCC isolation to disable outputs if either supply drops below 100mV.

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 enables either supply rail to be powered on or off in any order
• Ioff supports partial-power-down mode operation by disabling I/O output circuits to prevent backflow current
• VCC isolation feature disables all I/O outputs when either supply input is below 100mV or left floating

• 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 'G4' suffix indicates compliance with RoHS 3 standards and absence of halogenated flame retardants. Confirm the package type matches the required PCB footprint, typically TSSOP-24 for this suffix variant. Ensure the ordering information aligns with the specific revision SCES584D published by Texas Instruments.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for asynchronous communication between two data buses requiring voltage level translation. Ensure control inputs DIR and OE are supplied by VCCA. Unused I/O ports must be tied to logic HIGH or LOW to minimize power consumption. Verify that the operating temperature range meets the system requirements of -40°C to 85°C.
