MM74HCT373SJX

Latches Overview

The MM74HCT373SJX is an octal D-type transparent latch manufactured by Fairchild Semiconductor, utilizing advanced silicon-gate CMOS technology. It features three-state outputs capable of driving fifteen LS-TTL loads and operates within a supply voltage range of 4.5V to 5.5V. The device provides typical propagation delays of 20ns with low input current of 1µA maximum and quiescent current of 80µA maximum. Packaged in a 20-pin SOP format, it ensures compatibility with bus-oriented systems and includes internal protection diodes against static discharge damage on all inputs.

Latches Feature Summary

• Features three-state outputs that enter high impedance when output control is high
• Maintains TTL input and output characteristics for system compatibility
• Includes internal diode protection against static discharge on all inputs

Latches Applications

• Bus-oriented system data storage
• Register applications requiring transparent latching
• Buffering and bus driving interfaces

Latches Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required operating temperature range and logic family standards for your circuit design. Cross-reference the part number with current distributor listings to confirm availability status and lead times prior to procurement planning.

Latches Selection Notes

Select this component when designing circuits requiring octal data latching with high-impedance bus isolation capabilities. The CMOS construction offers low power consumption suitable for battery-operated or heat-sensitive environments. Verify that the drive strength meets the load requirements of connected LS-TTL devices and that the supply voltage remains within the specified operational limits.

Latches Part Context

This device belongs to the 74HCT logic family, bridging CMOS performance with TTL compatibility. It serves as a standard solution for digital data retention in microprocessor-based systems. The octal configuration allows for efficient handling of wide data buses, reducing component count compared to single-bit alternatives while maintaining signal integrity across industrial temperature ranges.

Latches Replacement Considerations

Consider the MM74HCT373SJ or other variants within the same 74HCT373 series from Fairchild or ON Semiconductor for direct pin-compatible substitution. Verify electrical parameters such as propagation delay and output drive current to ensure functional equivalence in existing designs.
