74ACT16374DLRG4

Overview

The SN74ACT16374DLRG4 is a Texas Instruments logic component featuring two independent octal D-type flip-flops. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 65 MHz. The device provides non-inverting outputs with three-state capability, delivering high drive currents of 24mA for both sourcing and sinking. It exhibits a maximum propagation delay of 8.8ns at 5V with a 50pF load and maintains a low static current of 8µA. Designed for surface-mount applications, it is housed in a 48-SSOP package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Contains two independent octal D-type flip-flops for parallel data storage
• Features three-state outputs to facilitate bus-oriented systems
• Provides high-drive output capability suitable for direct interface to CMOS, NMOS, and TTL loads

Applications

• Parallel-to-serial converters
• Bus-oriented memory register implementations
• Clock-domain crossing synchronization circuits

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free packaging compliant with RoHS standards when ordering. Confirm that the 48-SSOP package dimensions align with PCB footprint requirements. Ensure the 4.5V to 5.5V supply voltage constraints are met by the system design. Check for any recent Product Change Notifications regarding assembly materials or pin configurations before finalizing procurement.

Selection Notes

Select this component when designing 5V logic systems requiring dual 8-bit registers with high-speed performance up to 65 MHz. The ACT series offers faster switching speeds compared to standard HC logic while maintaining compatible input/output levels. Consider the 48-SSOP package for space-constrained surface-mount designs. Verify that the 24mA drive current meets the fan-out requirements of the connected downstream logic gates.

Part Context

This part belongs to the Texas Instruments 74ACT family of advanced CMOS logic devices. The 74ACT16374 serves as a dual octal D-type flip-flop variant within the broader 74ACT logic portfolio. It shares functional similarities with other 74ACT components but is distinct from the 74AHC and 74LVC families due to its specific 5V operation and speed characteristics. The base model number is 74ACT16374.

Replacement Considerations

The SN74ACT16374DLR is the non-green equivalent without the G4 suffix. For lower voltage applications, consider the SN74AUC16374 series. Direct pin-compatible replacements may include other manufacturers' 74ACT16374 variants, provided they meet the same electrical specifications.
