SN74LVTT244DBLE

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTT244DBLE is an octal buffer and line driver from Texas Instruments, belonging to the LVT logic series. It features eight non-inverting input lines and three-state outputs, housed in a SOIC-20 package. The device operates within a supply voltage range of 2.7 V to 3.6 V. Key electrical specifications include a high-level output current of -32 mA and a low-level output current of 64 mA. Static current is specified at 5 mA, with a typical propagation delay of 2.3 ns at 3.3 V. The component supports surface-mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DBLE' against official Texas Instruments documentation to confirm pinout compatibility and package dimensions. Ensure that the ordering information matches the required tape-and-reel or tube packaging format for your assembly process. Cross-reference the RoHS compliance status and lead-free designation with the latest manufacturer datasheet to meet environmental regulatory standards for your production facility.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with three-state outputs under 3.3V logic levels. Consider the 2.3 ns propagation delay for timing-sensitive applications. Evaluate the SOIC-20 package constraints against available PCB real estate. Compare performance metrics such as output drive strength against alternative LVT series devices if higher current capacity or different voltage tolerances are required for the specific application environment.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTxxxB family of octal buffers and drivers. It shares functional similarities with parts like the SN74LVT244BDWG4 but differs in package type and specific suffix designations. The LVT series is designed for low-voltage applications, offering performance comparable to earlier TTL standards while operating at lower power consumption levels suitable for modern portable and embedded electronics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes may include other variants within the SN74LVT244B family, such as SN74LVT244BDW or SN74LVT244BPWR, depending on the required package style (SOIC vs. TSSOP) and reel configuration. Verify pin-to-pin compatibility before substitution.
