SN74LS74AML1

Flip Flops Overview

The SN74LS74AML1 is a dual D-type positive-edge-triggered flip-flop manufactured by onsemi. It utilizes Low Power Schottky (LPS) TTL circuitry to achieve high-speed operation within the standard 74LS logic family. The device contains two independent flip-flops, each featuring dedicated data input (D), clock input (CP), asynchronous active-low preset (PRE), and asynchronous active-low clear (CLR) inputs. Complementary outputs Q and Q-bar are provided for each stage. The component operates with a nominal supply voltage of 5V and supports parallel data transfer synchronized to the rising edge of the clock signal.

Flip Flops Feature Summary

• Dual independent D-type flip-flop configuration
• Asynchronous active-low preset and clear controls
• Positive-edge clock triggering mechanism
• Complementary Q and Q-bar output stages

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Digital state storage and memory elements
• Synchronization of signals across different clock domains
• Frequency division and counter construction

Flip Flops Procurement Notes

Verify that the specific suffix 'AML1' corresponds to the intended package type and tape-and-reel configuration as defined in the official datasheet. Confirm RoHS compliance status and temperature range specifications against the manufacturer's current product change notices. Ensure pinout compatibility with existing PCB footprints before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems requiring robust noise immunity and moderate switching speeds typical of LSTTL technology. It is suitable for applications interfacing with other 74LS series devices. Consider alternative HC or HCT families if lower power consumption or CMOS compatibility is required instead of the inherent characteristics of Low Power Schottky logic.

Flip Flops Part Context

This part belongs to the widely adopted 74LS series of digital logic integrated circuits. The SN74LS74 variant specifically provides essential sequential logic functionality. Its design allows for reliable data latching in microprocessor systems and digital control loops, serving as a fundamental building block for complex timing and sequencing operations in electronic hardware.

Flip Flops Replacement Considerations

Compatible substitutes include the SN74LS74N from Texas Instruments and the MC74LS74P from onsemi. These parts maintain identical logical functions and pinouts. Verify that any replacement matches the specific AML1 packaging requirements if surface-mount or specific reel configurations are mandatory for the assembly process.
