74LVT640PW,118

Buffers, Drivers, Receivers, Transceivers Overview

The 74LVT640PW,118 is an octal transceiver from the LVT logic family, manufactured by Nexperia. It features eight bidirectional data paths with inverting functionality and three-state outputs. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports direct interface with TTL levels. Key electrical characteristics include an output capability of +64 mA and -32 mA, with bus-hold inputs eliminating external pull-up requirements. It complies with JEDEC standards JESD8C for 2.7 V to 3.6 V operation and offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bidirectional bus interface with inverting direction control via DIR pin.
• Three-state outputs controlled by OE pin, enabling partial power-down mode.
• Bus-hold data inputs eliminate need for external pull-up resistors on unused inputs.
• Overvoltage tolerant inputs up to 5.5 V, permitting live insertion/extraction.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the suffix ,118 to ensure correct packaging configuration. Confirm RoHS compliance status and REACH registration details against current regulatory databases. Check for any specific PCN notifications regarding assembly or wafer fab transfers that may affect long-term availability or marking changes prior to final procurement authorization.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-drive current octal transceivers operating at 3.3 V. Ensure input voltages do not exceed the 5.5 V overvoltage tolerance limit. Verify that the TSSOP-20 package fits the PCB footprint constraints. Consider the inverting logic function in signal path design compared to non-inverting alternatives like the 74LVC245.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74LVT series, designed for low-voltage applications with enhanced drive strength. It serves as a bridge between different voltage domains while maintaining signal integrity through bus-hold capabilities. The device is suitable for high-speed digital interfaces where reliable data transmission across multiple lines is critical.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other octal transceivers with similar voltage ranges and drive currents. Verify pin compatibility and logic inversion polarity before substitution. Non-inverting equivalents such as the 74LVC245 require functional adaptation in the circuit design.
