MC74AC273MELG

Flip Flops Overview

The MC74AC273MELG is an octal D-type flip-flop logic device manufactured by onsemi, belonging to the 74AC series. It integrates eight edge-triggered D-type flip-flops with individual D inputs and Q outputs within a single package. The component operates within a supply voltage range of 2 V to 6 V and features buffered common clock and asynchronous master reset inputs. It utilizes a SO EIAJ surface-mount package and supports installation via SMD/SMT mounting styles. The device ensures reliable data storage and transfer in digital circuits.

Flip Flops Feature Summary

• Integrates eight edge-triggered D-type flip-flops for parallel data handling
• Features buffered common clock and asynchronous master reset inputs
• Provides high drive capability with output currents sourcing and sinking 24 mA

Flip Flops Applications

• Buffering for MOS microprocessor systems
• Memory interface buffering applications
• General-purpose digital data storage circuits

Flip Flops Procurement Notes

Verify the specific package designation matches the required SO EIAJ form factor during procurement. Confirm that the operating temperature range aligns with system requirements, as this variant supports extended industrial conditions. Ensure compatibility with the 2 V to 6 V supply voltage window for proper logic level operation. Cross-reference the manufacturer part number to distinguish between standard AC and ACT input compatibility variants if TTL levels are involved.

Flip Flops Selection Notes

Select this component when designing systems requiring octal data latching without three-state outputs. The MC74AC273 differs from the MC74AC374, which offers three-state outputs, and the MC74AC373, which functions as a transparent latch. Choose this part for applications needing simultaneous resetting of all flip-flops via a dedicated master reset line. Consider the propagation delay characteristics relative to system clock speeds to ensure timing integrity.

Flip Flops Part Context

This device is part of the broader MC74AC273 family, which includes variants such as MC74AC273DTR2G and MC74AC273DWG. These variations primarily differ in packaging options and reel specifications while maintaining identical logical functionality. The MC74AC273MELG specifically denotes the SO EIAJ package configuration. All members of this family share the core specification of eight edge-triggered D-type flip-flops with buffered control inputs.
