74LCXH16374MTDX

Overview

The Fairchild Semiconductor 74LCXH16374MTDX is a dual eight-bit D-type flip-flop integrated circuit featuring tri-state outputs. It operates within a supply voltage range of 2V to 3.6V and utilizes a 48-TFSOP package with a width of 6.10mm. The device contains two independent elements, each handling eight bits of data, designed for positive edge triggering. It supports bus-oriented applications through its non-inverted output configuration.

Feature Summary

• Dual eight-bit architecture providing two independent storage elements
• Tri-state output capability for efficient bus management
• Positive edge-triggered D-type operation for precise timing control

Applications

• Bus-oriented data storage systems
• High-speed digital signal processing interfaces
• Memory buffer circuits in consumer electronics

Procurement Notes

Verify the specific manufacturer designation, as Fairchild Semiconductor logic products are often distributed under the onsemi brand following corporate restructuring. Confirm the exact suffix 'MTDX' corresponds to the required tape-and-reel packaging format rather than bulk units. Ensure compatibility with the 2V to 3.6V operating voltage range for your target application design.

Selection Notes

Select this component when a compact solution for storing sixteen bits of data with high-impedance states is required. The TFSOP package offers a space-efficient footprint for dense PCB layouts. Consider the 3.6V maximum supply limit when integrating with higher voltage logic families, ensuring appropriate level shifting if necessary for system interoperability.

Part Context

This part belongs to the 74LCXH series, which represents low-voltage CMOS technology optimized for performance at reduced supply voltages. The LCXH family typically bridges the gap between standard LVCMOS and higher-speed variants, offering improved power consumption characteristics while maintaining robust noise immunity for portable and battery-operated devices.

Replacement Considerations

Direct substitutes include other dual eight-bit D-type flip-flops with tri-state outputs in compatible packages. Verify pinout compatibility before swapping. Alternative manufacturers may offer equivalent functionality under different naming conventions, requiring careful cross-reference of electrical specifications and physical dimensions.
