74LVT240PW,112

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74LVT240PW,112 is a 3.3 V octal inverting buffer and line driver featuring 3-state outputs housed in a TSSOP20 package. It operates within a supply voltage range of 2.7 V to 3.6 V and supports overvoltage tolerant inputs up to 5.5 V. The device provides high output drive capabilities with +64 mA low-level and -32 mA high-level currents. Propagation delays are specified at 2.5 ns typical at 3.3 V. It includes bus hold inputs and IOFF circuitry for partial power-down mode operation.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bus interface with dual independent output enables controlling four outputs each
• BiCMOS technology delivering high speed performance and robust output drive capability
• Bus hold data inputs eliminate the need for external pull-up resistors on unused lines
• IOFF circuitry enables partial power-down mode to minimize system current consumption

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data bus buffering applications
• Line driving for complex PCB layouts
• Systems requiring live insertion and extraction support
• Interfaces between 3.3 V logic and 5 V systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple variants. Confirm the temperature range aligns with operational requirements, noting that standard versions cover -40 °C to +85 °C. Check current production status and longevity program details directly with Nexperia or authorized distributors before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an inverting function is required for octal data buses. Ensure the design utilizes the dual enable pins to manage separate 4-bit sections if needed. Verify that the 5.5 V input tolerance meets the source signal levels. Consider the TSSOP20 footprint constraints during layout planning.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74LVT logic family, designed for 3.3 V applications. It serves as a high-performance alternative to older logic families, offering faster switching speeds and lower power dissipation. The octal configuration allows for efficient management of wide data paths in digital systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes include the 74LVT240D variant in an SO20 package. Other 74LVT series buffers may serve as functional replacements if package differences are acceptable.
