74VHC112MTC

Overview

The Fairchild Semiconductor 74VHC112MTC is a dual J-K flip-flop integrated circuit belonging to the 74VHC logic series. It features two independent elements, each with one bit per element, housed in a 16-TSSOP surface-mount package. The device operates on a supply voltage range of 2V to 5.5V and supports negative edge triggering. Key electrical specifications include a maximum propagation delay of 10.5ns at 5V with 50pF load capacitance, output currents of 8mA for both high and low states, and a static current of 2µA. It functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Dual J-K flip-flops with preset and clear functionality
• Negative edge-triggered synchronous state changes
• Complementary output types

Applications

• Digital data storage circuits
• Shift registers
• Frequency dividers

Procurement Notes

Verify the manufacturer origin carefully, as this component is produced by multiple vendors including onsemi and Texas Instruments under identical part numbers. Confirm the specific datasheet version matches your design requirements. Ensure the 16-TSSOP package dimensions align with your PCB footprint. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a dual J-K configuration with complementary outputs is required in a compact surface-mount form factor. The 74VHC series offers high-speed performance suitable for applications needing fast switching speeds. Consider the 2V to 5.5V supply range compatibility with your system's voltage levels before finalizing the selection.

Part Context

This component is part of the broader 74VHC family of high-speed CMOS logic devices. It shares functional similarities with other J-K flip-flops like the 74VHC112MX but differs in packaging. The TSSOP variant provides a smaller profile compared to SOIC packages, making it suitable for space-constrained designs requiring dual flip-flop capabilities.

Replacement Considerations

The 74VHC112MTCX is a verified substitute offering identical functionality in a tape-and-reel or cut-tape format. Other equivalents include the 74VHC112MX from different manufacturers, provided the pinout and electrical characteristics remain compatible.
