74LVT16240MTDX

Overview

The Fairchild Semiconductor 74LVT16240MTDX is a 16-bit bus driver belonging to the LVT (Low Voltage TTL) logic series. It features inverted outputs and operates within a supply voltage range of 2.7V to 3.6V. The device utilizes a 48-pin Thin Shrink Small Outline Package (TSSOP) with a 0.5mm pitch. It supports an operating temperature range from -40°C to +85°C and includes three-state outputs for effective bus management in digital systems.

Feature Summary

• Provides 16-bit bidirectional data buffering with inverted output polarity
• Supports low voltage operation compatible with 3.3V logic systems
• Features three-state outputs to prevent bus contention during inactive states

Applications

• High-density memory buffer applications
• Clock drivers and timing signal distribution
• Bus-oriented architectural interconnects

Procurement Notes

Verify the specific suffix 'MTDX' against the manufacturer's current datasheet to confirm package type, tape-and-reel specifications, and RoHS compliance status. Ensure the ordering code matches the exact pin configuration and moisture sensitivity level required for your assembly process. Cross-reference with Diodes Incorporated documentation as they are the current manufacturer.

Selection Notes

Select this component when a 16-bit wide interface requires inversion and low-voltage compatibility. Compare propagation delay and drive strength against other LVT or LVTH variants if signal integrity at higher frequencies is critical. Ensure the system power supply remains stable within the 2.7V to 3.6V range to maintain guaranteed switching characteristics.

Part Context

This part belongs to the widely adopted 74LVT logic family, designed to bridge older TTL-compatible designs with modern low-voltage CMOS technologies. The 16240 designation typically indicates a 16-bit buffer/driver configuration. Fairchild Semiconductor, now part of Diodes Incorporated, continues to support this legacy standard for industrial and consumer electronics.

Replacement Considerations

Check for equivalents such as the PI74LPT16240AX or IDT74FCT162240ETPFG. Verify that substitute parts match the 48-pin TSSOP footprint and electrical parameters like output drive current and propagation delay before implementation.
