74LVT2240SJX

Overview

The onsemi 74LVT2240SJX is an octal buffer and line driver belonging to the LVT logic series. It features eight non-inverting inputs and outputs housed in a 20-SOP package. The device operates within a supply voltage range of 2.7 V to 3.6 V. Key electrical parameters include a propagation delay of 5.3 ns at 2.7 V and 4.4 ns at 3.3 V. Output drive capabilities are specified as -12 mA for high-level and 12 mA for low-level currents. Static current is 190 uA, with a maximum power dissipation of 180 mW. The component supports surface mount installation and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Provides octal buffering and line driving functionality with non-inverting signal paths
• Features three-state outputs for bus-oriented applications
• Operates within a low-voltage supply range suitable for 3.3 V systems

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffering
• Capacitively loaded circuits

Procurement Notes

Verify the specific suffix SJX against the official datasheet to confirm pinout and packaging details. Confirm RoHS compliance status through manufacturer documentation. Check for End-of-Life notices or production discontinuation announcements prior to finalizing procurement plans. Ensure the supplier provides valid traceability documents matching the onsemi manufacturing origin.

Selection Notes

Select this component when designing systems requiring octal buffering with 3.3 V logic levels. Compare propagation delays and output drive strengths against alternative LVT series parts if higher speed or current is needed. Verify that the SOP-20 package fits the available PCB footprint constraints. Ensure input voltage levels match the system's logic standards to prevent undefined states.

Part Context

This part belongs to the 74LVT2244 family of octal buffers and line drivers manufactured by onsemi. It shares functional similarities with other LVT series components but is distinguished by its specific package type and electrical characteristics. The LVT series is designed for low-voltage applications, offering performance comparable to older LVX or LVC families while maintaining compatibility with 3.3 V systems.
