74ALVC16374MTDX

Overview

The onsemi 74ALVC16374MTDX is a dual 8-bit D-type flip-flop integrated circuit belonging to the 74ALVC logic family. It features positive-edge triggering and tri-state non-inverting outputs, designed for high-speed digital applications. The device operates within a supply voltage range of 1.65V to 3.6V, ensuring compatibility with various low-voltage systems. Key electrical parameters include a maximum propagation delay of 3.5ns at 3.3V with a 50pF load, supporting clock frequencies up to 250MHz. It provides robust output drive capabilities with 24mA source and sink currents while maintaining a low static current of 40µA. The component is housed in a 48-TFSOP package.

Feature Summary

• Positive-edge triggered operation ensures precise data capture synchronized with clock signals.
• Tri-state non-inverting outputs allow for effective bus driving and signal isolation.
• High-speed performance capability supports data rates up to 250MHz.

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Memory address latching
• Buffering and registration in high-speed digital systems

Procurement Notes

Verify the specific suffix 'MTDX' against official manufacturer documentation to confirm tape-and-reel packaging specifications. Ensure that the requested quantity aligns with standard reel sizes defined in the datasheet. Cross-reference the part number with the latest RoHS compliance status and material declarations provided by onsemi to meet environmental regulatory requirements for your specific region.

Selection Notes

Select this component when designing systems requiring high-speed parallel data storage with minimal propagation delay. The ALVC series offers superior speed compared to standard LVCMOS options while maintaining low power consumption. Consider the 48-pin TFSOP footprint for PCB layout constraints. Evaluate the 24mA output drive strength against the capacitive load of the destination inputs to ensure signal integrity at the target operating frequency.

Part Context

This device is part of the broader 74ALVC16374 family, which includes variants with different packaging or suffixes such as the obsolete 74ALVC16374MTD. The MTDX designation specifically indicates the tape-and-reel configuration suitable for automated surface-mount assembly processes. It shares core logical functionality with other members of the 74ALVC16xx series but differs in physical delivery format and potentially minor mechanical tolerances defined by the manufacturer.

Replacement Considerations

Public confirmed substitute part numbers include SN74ALVCH162374GR and SN74ALVCH16374DGGR from Texas Instruments. Verify pinout compatibility and electrical parameter equivalence before substitution. Note that alternative manufacturers may have slight variations in propagation delay or output drive characteristics that require circuit validation.
