SN74LV8T245QPWRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV8T245-Q1 is an automotive-grade octal bus transceiver with three-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 between A and B buses, controlled by DIR and OE pins. It features enhanced input thresholds for up-translation (e.g., 1.2 V to 1.8 V) and 5.5 V tolerant inputs for down-translation. Propagation delays range from approximately 4.5 ns at 5 V to 25.1 ns at 1.8 V under specific load conditions.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant (RKS, DGS, or PW) required for your design, as pinout dimensions differ. Confirm that the Q1 suffix aligns with your automotive qualification requirements. Ensure input transition rates meet the specified limits to prevent oscillation. Check absolute maximum ratings against your system's voltage spikes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between different voltage domains within a single power rail environment. It is suitable for designs requiring robust level shifting without dual supplies. Consider the propagation delay specifications relative to your system clock speeds. Evaluate thermal performance if operating near maximum current limits.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to Texas Instruments' LVxT family of logic devices designed for voltage level translation. It complements other bus transceivers by offering integrated level shifting in a compact form factor. The Q1 designation indicates it meets automotive reliability standards, distinguishing it from standard commercial grade counterparts.
