74LCX374MSA

Overview

The Fairchild Semiconductor 74LCX374MSA is an octal D-type flip-flop featuring three-state outputs, designed for bus-oriented applications. It operates within a supply voltage range of 2V to 3.6V and utilizes advanced CMOS technology for high-speed performance with low power dissipation. The device contains eight D-type flip-flops with separate data inputs and a common clock input. It is housed in a 20-SSOP package suitable for surface-mount assembly.

Feature Summary

• Octal D-type flip-flop architecture with three-state outputs
• High-speed operation utilizing advanced CMOS technology
• Low power dissipation characteristics
• TTL-compatible inputs for system interfacing

Applications

• Bus-oriented data storage systems
• Parallel-to-serial data conversion circuits
• General-purpose memory registers
• Timing and synchronization logic modules

Procurement Notes

Verify the specific manufacturer designation as the part number may be associated with Fairchild Semiconductor or onsemi following corporate restructuring. Confirm the exact suffix requirements for tape and reel versus tube packaging if applicable to your manufacturing process. Ensure compliance with RoHS directives and check for any lead-free status updates relevant to current production batches.

Selection Notes

Select this component when an octal storage element with tri-state capability is required for low-voltage digital designs. It is appropriate for systems operating between 2V and 3.6V where bus isolation is necessary. Consider the 20-SSOP package dimensions for PCB layout constraints. Verify that the input voltage levels are compatible with the TTL-compatible specification of the driving source.

Part Context

This component belongs to the 74LCX series of low-voltage CMOS logic devices. The LCX family provides performance comparable to standard TTL while operating at lower supply voltages. The 74LCX374 variant specifically offers octal configuration with three-state outputs, distinguishing it from non-inverting buffers or inverters within the same logical family.

Replacement Considerations

Public confirmed substitute part numbers include SN74LVC574ADBR from Texas Instruments and CLVC374AQPWRG4Q1 from Texas Instruments. These alternatives provide similar functional characteristics for octal D-type flip-flops with three-state outputs.
