74LVX112MTC

Overview

The Fairchild Semiconductor 74LVX112MTC is a dual J-K flip-flop integrated circuit manufactured by ON Semiconductor. It operates within a voltage range of 2.0V to 3.6V and features independent inputs for J, K, PRESET, CLEAR, and CLOCK, alongside Q and Q outputs. The device utilizes negative edge triggering and provides output currents of 4mA at both high and low states. It is housed in a 16-TSSOP package with a width of 4.40mm and supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Dual J-K flip-flop architecture with independent control inputs
• Negative edge-triggered operation for precise timing synchronization
• Low voltage compatibility supporting 2.0V to 3.6V power supplies

Applications

• Digital data storage and shift register circuits
• Frequency division and counter logic designs
• State machine implementation in low-voltage systems

Procurement Notes

Verify the manufacturer marking matches Fairchild or ON Semiconductor standards. Confirm the 16-TSSOP package dimensions align with JEDEC MO-153 specifications. Ensure the component meets RoHS compliance requirements for lead-free manufacturing. Check datasheet revisions to confirm electrical characteristics match system design constraints.

Selection Notes

Select this component when designing systems requiring dual J-K functionality with low power consumption. The 2.0V minimum supply voltage makes it suitable for battery-operated devices. Verify that the 4mA drive capability meets load requirements. Consider the -40°C to 85°C range for industrial applications.

Part Context

This part belongs to the 74LVX series, which offers low-voltage CMOS performance. It serves as a standard logic solution for sequential circuits. The TSSOP package provides space-efficient mounting for surface-mount assembly processes. It replaces older TTL-based flip-flops in modern low-power digital designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the same LVX family. Verify equivalent switching speeds and output drive strengths. Ensure thermal performance remains consistent under similar operating conditions.
