SN74LVTH244ADBRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH244ADBRE4 is an octal buffer and line driver from Texas Instruments, utilizing the LVTH advanced low-voltage CMOS technology. It features eight non-inverting channels with three-state outputs, housed in a 20-pin SSOP package. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports input voltages up to 5 V, enabling level translation between 3.3 V and 5 V domains. Key electrical parameters include a propagation delay of 2.3 ns at 3.3 V, high-level output current of -32 mA, and low-level output current of 64 mA. It functions across a commercial temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the SSOP-20 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your application's environmental constraints. Cross-reference the datasheet revision date to confirm the latest electrical characteristics and pinout definitions before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-speed buffering with mixed voltage levels. It is suitable for applications needing strong drive strength to handle capacitive loads or long traces. Consider the SSOP-20 package size relative to available board space. Verify that the 3.3 V supply voltage aligns with your system architecture and that the 5 V input tolerance covers all connected signal sources.
