MC74LVX373DWR2G

Latches Overview

The MC74LVX373DWR2G is an advanced high-speed CMOS octal D-type latch with three-state outputs manufactured by onsemi. It operates within a DC supply voltage range of 2.0 V to 3.6 V and supports an operating temperature from -40°C to +85°C. The device features inputs that tolerate voltages up to 7.0 V, enabling interface between 5.0 V and 3.0 V systems. Propagation delay (tPD) is typically 5.8 ns at VCC = 3.3 V with a 15 pF load, while quiescent supply current (ICC) is maximized at 4 µA at 25°C.

Latches Feature Summary

• Features five-volt tolerant inputs allowing direct interfacing between 5.0 V and 3.0 V logic systems.
• Provides power-down protection on inputs to prevent excessive current draw during low-power states.
• Includes balanced propagation delays for consistent signal timing across all eight channels.
• Offers robust electrostatic discharge performance exceeding 2000 V via the human body model.

Latches Applications

• Bus-oriented memory mapping
• Working registers
• Shift registers

Latches Procurement Notes

Verify the specific ordering suffix 'DW' corresponds to the SOIC-20 package when sourcing components. Confirm RoHS compliance and lead-free status as indicated in the manufacturer's documentation. Ensure input voltage levels do not exceed the absolute maximum ratings to maintain device reliability and functionality.

Latches Selection Notes

Select this component for applications requiring low power dissipation and high-speed data latching in portable or battery-operated devices. The wide input voltage tolerance makes it suitable for mixed-voltage environments where 5V signals must interface with lower voltage logic cores without additional level shifting circuitry.

Latches Part Context

This part belongs to the MC74LVX373 series of octal transparent latches. It shares functional compatibility with other standard logic families while offering improved speed and lower power consumption characteristics typical of the LVX technology line designed for low-voltage digital applications.
