SN74LV245ARKSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV245ARKSR is an octal bus transceiver with three-state outputs manufactured by Texas Instruments. It operates on a single 2-V to 5.5-V VCC supply and supports mixed-mode voltage operation across all ports. The device features a maximum propagation delay of 6.5 ns at 5 V and includes Ioff circuitry for partial-power-down mode. It utilizes a 20-pin VQFN (RKS) package measuring 4.5 mm x 2.5 mm.

Buffers, Drivers, Receivers, Transceivers Feature Summary

Supports asynchronous bidirectional data transmission between two buses
Enables down voltage translation from 5 V to 3.3 V via overvoltage-tolerant inputs
Includes Ioff circuitry to prevent damaging current backflow during power-down
Provides high electrostatic discharge protection exceeding JESD 22 standards

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific RKS package variant matches the required footprint dimensions of 4.5 mm by 2.5 mm. Confirm that the operating temperature range of -40°C to 125°C aligns with system thermal constraints. Ensure input pins are tied to valid logic levels to prevent floating states during operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low-drive CMOS technology to minimize output ringing. It is suitable for bus-interface designs where slow edge rates help reduce overshoot and undershoot. Verify compatibility with mixed-voltage systems utilizing both 3.3 V and 5 V logic levels.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV245A family of octal bus transceivers. The RKS suffix designates the specific 20-pin Very Thin Quad Flat No-Lead (VQFN) package option. This family provides balanced output drive capabilities for general-purpose digital logic interfacing.
