74LVTH16374MTDX

Overview

The Fairchild Semiconductor 74LVTH16374MTDX is a low-voltage 16-bit D-type flip-flop featuring three-state outputs, designed for bus-oriented applications. It utilizes advanced BiCMOS technology to achieve high-speed operation comparable to 5V ABT logic while maintaining low power dissipation. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports TTL interface capabilities in 5V environments. Key electrical parameters include a propagation delay of 5.2 ns, an output source current of -32 mA, and an output sink current of 64 mA. It is housed in a 48-SSOP package.

Feature Summary

• Features bus-hold data inputs that eliminate the need for external pull-up resistors to maintain unused input states.
• Provides power-up and power-down high-impedance states to ensure glitch-free bus loading during transitions.
• Supports live insertion and extraction operations without causing system interference.

Applications

• Bus-oriented digital systems requiring 16-bit data storage
• Low-voltage memory interface circuits
• High-speed data buffering applications

Procurement Notes

Verify the specific suffix MTDX against official onsemi/Fairchild documentation to confirm the tape-and-reel packaging configuration. Confirm RoHS compliance status and check for any Product Change Notifications (PCN) regarding manufacturing site or material changes. Ensure the component meets the required operating temperature range specifications for the intended application environment.

Selection Notes

Select this component when a 16-bit register with three-state outputs is required for low-voltage systems. The bus-hold feature simplifies design by removing external pull-ups for unused lines. Compare performance metrics such as propagation delay and drive strength against alternative LVT series devices to ensure compatibility with system timing requirements and load conditions.

Part Context

This part belongs to the 74LVTH series of low-voltage CMOS logic devices manufactured by Fairchild Semiconductor, now part of onsemi. The LVTH designation indicates the inclusion of bus-hold functionality, distinguishing it from the standard LVT series which lacks this feature. These devices are engineered for high-speed performance in portable and battery-operated applications.

Replacement Considerations

The 74LVT16374MTDX serves as a functional substitute if bus-hold inputs are not required. Verify pinout compatibility and electrical characteristics before substitution.
