74LVTH162374MEX

Overview

The onsemi 74LVTH162374MEX is a dual 8-bit D-type flip-flop logic integrated circuit belonging to the 74LVTH series. It features positive-edge triggering and tri-state outputs in a non-inverting configuration. The device operates within a supply voltage range of 2.7V to 3.6V, with a maximum propagation delay of 5.0ns at 3.3V with 50pF load. It supports a clock frequency of 200 MHz and provides output drive currents of 32mA high and 64mA low. Packaged in a 48-BSSOP (0.295", 7.50mm wide) surface-mount format, it functions across an operating temperature range of -40°C to 85°C.

Feature Summary

• Dual 8-bit architecture providing two independent D-type flip-flops per package
• Positive-edge triggered data latching with tri-state output control
• High-speed operation supporting up to 200 MHz clock frequencies
• Robust output drive capability with asymmetric current sourcing and sinking

Applications

• Parallel-to-serial data conversion circuits
• Buffering and register stages in high-speed digital systems
• Interface logic for memory subsystems requiring level translation
• Data acquisition systems utilizing parallel input capture

Procurement Notes

This component is officially obsolete and no longer manufactured by onsemi. Procurement must rely on available substitute part numbers from other manufacturers such as Texas Instruments or Nexperia. Verify that replacement devices match the original pinout, voltage specifications, and package dimensions to ensure compatibility with existing board layouts. Check manufacturer datasheets for any functional differences in timing characteristics or electrical limits before integration.

Selection Notes

Select this component for applications requiring dual 8-bit storage with high-speed performance and strong output drive capabilities. The 74LVTH series is suitable for 3.3V systems needing robust signal integrity. Consider the 48-BSSOP package constraints for PCB space. Due to its obsolete status, prioritize substitutes with identical pin configurations and verified electrical parameters to maintain system reliability without redesigning the hardware interface.

Part Context

The 74LVTH162374MEX belongs to onsemi's 74LVTH family of high-voltage threshold logic devices. This series bridges the gap between standard LVCMOS and LVTTL interfaces, offering improved noise immunity and drive strength. The specific model integrates two 8-bit registers, making it a compact solution for wide-data-path applications compared to single-bit alternatives.

Replacement Considerations

Confirmed public substitutes include SN74LVTH16374DGGR and CLVTH16374IDLREP. Verify pin compatibility and electrical specs against the original datasheet before substitution.
