SN74LV8T245DGSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV8T245DGSR is an octal bus transceiver with 3-state outputs and logic level shifting capabilities. It operates on a single supply voltage ranging from 1.6 V to 5.5 V. The device supports bidirectional data transfer controlled by DIR and OE pins, enabling up-translation (e.g., 1.2 V to 1.8 V) and down-translation (e.g., 5.0 V to 3.3 V). It features 5.5-V tolerant inputs, balanced CMOS outputs, and latch-up performance exceeding 250 mA per JESD 17. Data rates reach up to 150 Mbps at 5 V or 3.3 V VCC.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package suffix 'DGSR' corresponds to the DGS (VSSOP, 20-pin) variant when ordering. Confirm that the reel quantity matches project requirements. Ensure ESD precautions are followed during handling as specified in the datasheet. Check for RoHS compliance status if required by assembly standards.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional level shifting between disparate voltage domains is required within a single supply range. It is suitable for interfaces where signal integrity must be maintained across varying load conditions. Consider thermal dissipation characteristics if operating near maximum temperature limits. Verify input transition rates meet system specifications to prevent excessive power consumption.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to Texas Instruments' LVxT family of logic devices, which integrate voltage level translation functions. The SN74LV8T245 serves as an octal version within this series, offering eight independent channels. It complements other variants like the SN74LVC8T245 by providing enhanced input threshold characteristics for lower voltage translation scenarios.
