MC74AC74MELG

Flip Flops Overview

The MC74AC74MELG is a dual D-type positive-edge-triggered flip-flop manufactured by onsemi. It features asynchronous set and clear inputs with complementary outputs (Q and Q̅). The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a maximum propagation delay of 10 ns at 5 V with 50 pF load, a clock frequency of 160 MHz, and output source/sink current capability of 24 mA. Static current consumption is 4 µA. It is housed in a 16-SOEIAJ surface-mount package.

Flip Flops Feature Summary

• Dual D-type flip-flops with positive-edge triggering mechanism
• Asynchronous set and clear inputs independent of clock signal
• Complementary outputs providing both Q and Q̅ states
• High noise immunity characteristics typical of CMOS devices

Flip Flops Applications

• Data storage and register applications
• Shift registers for serial-to-parallel conversion
• Frequency division circuits
• Timing control logic in digital systems

Flip Flops Procurement Notes

Verify the specific suffix MELG corresponds to the 16-SOEIAJ package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 2 V to 6 V operating voltage range. Check for any recent product change notifications affecting pinout or electrical specifications.

Flip Flops Selection Notes

Select this component for designs requiring dual edge-triggered storage elements with asynchronous control. Consider the 16-SOEIAJ package constraints for PCB layout. Evaluate the 160 MHz clock frequency against system timing requirements. Compare against MC74ACT74 variants if TTL-compatible input levels are necessary for interfacing with legacy logic families.

Flip Flops Part Context

This part belongs to the 74AC series of high-speed CMOS logic devices produced by onsemi. It is functionally equivalent to the standard 74AC74 specification but utilizes a specific leadless package format. The AC series offers faster switching speeds compared to older HC or HCT counterparts while maintaining low power consumption suitable for battery-operated applications.

Flip Flops FAQ

How do the asynchronous set and clear inputs affect the output state?

When the set input is low, the Q output goes high. When the clear input is low, the Q output goes low. These operations occur independently of the clock signal.

What is the trigger condition for data transfer?

Data is transferred from the D input to the Q output on the positive edge of the clock pulse. The trigger occurs when the clock input threshold voltage is exceeded.
