SN74LVCH245ARGYRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH245ARGYRG4 is an octal bus transceiver from the LVCH logic series, manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 2 V to 3.6 V. The device provides a propagation delay of 7 ns and supports TTL/CMOS input levels with LVTTL output levels. It delivers a low-level output current of 24 mA and a high-level output current of -24 mA. Housed in a VQFN-20 package, it functions as a non-inverting transceiver suitable for surface-mount installation across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the component matches the exact part number SN74LVCH245ARGYRG4 to avoid compatibility issues with existing circuit designs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring eight-bit wide data buses with low voltage operation between 2 V and 3.6 V. It is appropriate for applications needing moderate speed performance with a 7 ns propagation delay. Consider the VQFN-20 package constraints for PCB layout and thermal management during the selection process.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCH245A family of standard transceivers within Texas Instruments' logic IC portfolio.
