DM74LS27MX

Inverter Gates Overview

The DM74LS27MX is an octal D-type edge-triggered flip-flop manufactured by Fairchild Semiconductor, belonging to the LS logic series. It features eight independent D-type flip-flops with positive-edge triggering and non-inverting outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 20-pin SSOP package. Key electrical parameters include a propagation delay of 15 ns, a high-level output current of -2.6 mA, and a low-level output current of 24 mA. It functions reliably across an operating temperature range from 0°C to +70°C.

Inverter Gates Procurement Notes

Verify the specific manufacturer origin, as this part number may be sourced from onsemi or Fairchild Semiconductor depending on production history. Confirm the package type matches the required SSOP-20 footprint and ensure the logic family aligns with existing system design constraints. Check for RoHS compliance status if environmental regulations apply to the final assembly process.

Inverter Gates Selection Notes

Select this component when designing systems requiring multiple synchronized data storage elements without complex control logic. The LS series offers a balance of speed and power consumption suitable for general-purpose digital applications. Ensure the driving circuitry can handle the specified output current capabilities and that the clock signal meets the setup and hold time requirements defined in the official datasheet.

Inverter Gates Part Context

This component is part of the broader 74LS logic family, widely used in industrial and consumer electronics for basic sequential logic operations. The 'M' suffix typically denotes a surface-mount package variant, while 'DM' often indicates a specific manufacturing line or grade. It serves as a fundamental building block for creating state machines and memory buffers in standard TTL-compatible environments.

Inverter Gates Replacement Considerations

Compatible substitutes include the DM74ALS273MSA_Q for lower power consumption or the DM74LS374WM for similar functionality with different output configurations. Verify pin compatibility and electrical specifications before swapping components to ensure system integrity.
