74ALVCH16374TX

Overview

The onsemi 74ALVCH16374TX is a high-performance, low-voltage CMOS octal D-type flip-flop with 3-state outputs. It operates within a supply voltage range of 1.65V to 3.6V and features an enable input for data control. The device is designed for surface-mount applications in a 48-TFSOP package (0.240 inch width). It supports clock frequencies up to 250 MHz and offers propagation delays typical of the ALVCH series. The component includes latch-up protection exceeding 100 mA per JESD 78 standards.

Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering
• Three-state outputs for bus-driven system compatibility
• Low-voltage operation supporting 1.65V to 3.6V power supplies
• High-speed performance with 250 MHz clock frequency capability

Applications

• Parallel-to-serial data conversion circuits
• Clock domain crossing synchronization
• Bus-oriented memory register interfaces
• High-speed data buffering systems

Procurement Notes

Verify the specific ordering suffix 'TX' against the manufacturer's current datasheet to confirm packaging type, as suffixes often denote reel versus tube quantities or specific tape-and-reel configurations. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the part number with official onsemi distribution channels to avoid obsolete stock or counterfeit components, as logic families may have updated revisions.

Selection Notes

Select this component when designing low-voltage digital systems requiring octal storage with high-speed data handling. The 1.65V minimum supply makes it suitable for battery-powered or energy-efficient portable devices. Compare propagation delay specifications against system timing requirements to ensure signal integrity. Verify that the 48-TFSOP package dimensions align with the PCB footprint constraints and thermal management needs of the target application.

Part Context

This part belongs to the 74ALVCH series, representing advanced low-voltage CMOS technology from onsemi. It complements other logic family members by providing high-speed switching at reduced voltage levels compared to traditional 5V logic. The 74ALVCH16374TX serves as a standard solution for 8-bit data latching in modern embedded and communication hardware designs.

Replacement Considerations

Public confirmed substitutes include SN74ALVCH16374DGGR from Texas Instruments. Verify pinout compatibility and electrical parameter equivalence before substitution. Check if alternative packages require PCB layout adjustments.
