74LVTH16374MEAX

Overview

The 74LVTH16374MEAX is a Low Voltage 16-Bit D Flip-Flop with 3-STATE outputs manufactured by onsemi / Fairchild. It belongs to the LVTH logic series and features single-ended inputs and outputs in an SSOP-48 package. The device operates within a supply voltage range of 2.7 V to 3.6 V, supporting a minimum operating temperature of -40 C and a maximum of +85 C. Key electrical parameters include a propagation delay of 5.2 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA. The component contains two circuits and is classified as a non-inverting D-Type Flip-Flop.

Feature Summary

• Features 3-STATE outputs suitable for bus-oriented applications
• Includes bushold data inputs to eliminate external pull-up resistors for unused inputs
• Provides TTL interface capability to a 5V environment while operating at low voltage

Applications

• Bus oriented applications requiring byte control
• Mixed 3.3V and 5V system interfacing
• Low-voltage memory buffering

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific ordering suffix matches the required package and temperature grade. Check for recent Product Change Notifications (PCN) regarding manufacturing site or material changes. Ensure compliance with RoHS and lead-free status requirements for the target assembly process. Validate that the obsolete status does not impact long-term production viability.

Selection Notes

Select this component when designing systems requiring 16-bit parallel data storage with tri-state bus capabilities. The LVTH series offers high-speed operation similar to 5V ABT devices while maintaining low power dissipation. Consider the bushhold feature if external pull-ups are undesirable for floating inputs. Ensure the SSOP-48 package fits the PCB layout constraints and thermal requirements.

Part Context

This part is part of the 74LVTH16374 family, which includes variants like the 74LVT32374 offering 32-bit configurations. The 'MEAX' suffix typically denotes the SSOP-48 package and specific tape-and-reel or tube packaging options from Fairchild/onsemi. It serves as a bridge between low-voltage logic and traditional 5V TTL interfaces.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The datasheet indicates the product status is obsolete. Engineers should consult the manufacturer's official obsolescence notices for recommended next-generation replacements or alternative families.
