74ALVC16374DTR

Overview

The onsemi 74ALVC16374DTR is a high-speed, low-voltage CMOS octal D-type flip-flop with three-state outputs. It operates within a supply voltage range of 1.65V to 3.6V and features a maximum propagation delay of 3.5ns at 3.3V with 50pF load. The device contains two independent circuits, each handling eight bits, and supports clock frequencies up to 250 MHz. It utilizes a 48-TFSOP package and maintains a static current of 40 µA.

Feature Summary

• High-speed data storage with 250 MHz clock capability
• Low voltage operation from 1.65V to 3.6V
• Three-state outputs for bus-oriented systems
• Octal configuration with dual independent circuits

Applications

• Parallel data storage in high-speed digital systems
• Bus-oriented memory register architectures
• Clock domain crossing synchronization
• Data acquisition system interfaces

Procurement Notes

Verify the specific suffix 'DTR' against the manufacturer's official datasheet to confirm tape-and-reel packaging and moisture sensitivity level. Ensure compatibility with the required operating temperature range of -40°C to 85°C. Cross-reference pinout assignments with the 48-TFSOP package dimensions to prevent layout errors during integration.

Selection Notes

Select this component when designing systems requiring high-speed parallel data latching with low power consumption. The ALVC series offers superior speed compared to standard LVCMOS while maintaining lower voltage requirements than ACT/LVT families. Consider the 48-pin form factor for space-constrained PCB layouts requiring dense I/O connections.

Part Context

This part belongs to the 74ALVC logic family, known for advanced CMOS technology offering high speed and low power. It serves as an octal edge-triggered flip-flop, distinct from latches or registers with different control inputs. The DTR suffix indicates a specific reel packaging format for automated surface-mount assembly processes.

Replacement Considerations

Public confirmed substitutes include SN74ALVCH16374DGGR and SN74AUCH16374DGGR from Texas Instruments. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
