74LVT16374MTD

Overview

The Fairchild Semiconductor 74LVT16374MTD is a low-voltage 16-bit D-type flip-flop with three-state outputs, designed for bus-oriented applications. It utilizes advanced BiCMOS technology to achieve high-speed operation similar to 5V ABT while maintaining low power dissipation. The device operates at a supply voltage of 2.7V to 3.6V and supports a clock frequency up to 160 MHz. It features byte control with buffered clock and output enable signals shared across bytes. The component provides TTL interface capability to 5V environments and includes bus-hold data inputs to eliminate external pull-up resistors for unused inputs.

Feature Summary

• Advanced BiCMOS technology enables high-speed performance comparable to 5V ABT logic families while ensuring low power consumption.
• Integrated bus-hold data inputs maintain the state of unused pins without requiring external pull-up resistors.
• Provides system input and output interface capability compatible with 5V VCC environments despite low-voltage operation.
• Supports live insertion and extraction with power-up/down high-impedance states to ensure glitch-free bus loading.

Applications

• Bus-oriented memory mapping systems
• High-speed data buffering in low-voltage architectures
• Byte-controlled register interfaces

Procurement Notes

Verify the specific manufacturer designation as the model prefix indicates Fairchild Semiconductor, while current market listings often attribute this part number to onsemi following industry consolidation. Confirm RoHS compliance status and check for End-of-Life notifications or Product Change Notices regarding packaging or assembly sources before procurement planning.

Selection Notes

Select this component when designing systems requiring 16-bit parallel data storage with three-state bus compatibility at low voltages. It is suitable for applications needing byte-level control over data latching. Ensure the design accommodates the 2.7V to 3.6V supply range and considers the 48-pin TSSOP package constraints for PCB layout.

Part Context

This device belongs to the 74LVT logic family, which bridges the gap between standard 5V logic and modern low-voltage standards. It serves as a functional equivalent to the 74LS16374 but optimized for 3.3V systems. The MTD suffix denotes the 48-pin Thin Shrink Small Outline Package (TSSOP) variant.

Replacement Considerations

The 74LVTH16374 offers identical functionality but may vary in specific electrical characteristics or packaging options depending on the manufacturer. Verify pinout compatibility and electrical specifications against the original datasheet before substitution.
