What are the key features of 74FCT2373CTSOCTG4?
- Octal D-type transparent latch: data is passed when Latch Enable is high, latched when low — ideal for bus hold
- FCT logic family: fast CMOS with TTL-compatible inputs for high-speed backplane and bus driving applications
- 12 mA output sink current (Max I(ol) = 0.012 A) for robust fan-out drive capability on heavily loaded buses
- 20-pin SOIC (R-PDSO-G20) surface-mount package with 50 pF load capacitance and active-low output enable
What is 74FCT2373CTSOCTG4 used for?
The 74FCT2373CTSOCTG4 is commonly used as an address or data latch in microprocessor bus demultiplexing circuits, where 8-bit data must be captured and held stable while the bus transitions to a new cycle. Its transparent latch mode allows real-time pass-through during valid data windows, and the storage mode holds the last valid byte during address or control phases. The FCT family's fast switching speed and TTL-compatible inputs make it well-suited for VMEbus, ISA bus, and industrial backplane applications.

Frequently Asked Questions
Which designs are a good fit for 74FCT2373CTSOCTG4 from Texas Instruments?
74FCT2373CTSOCTG4 fits embedded electronics, industrial controls, instrumentation, and production repair builds that need 8-bit. Engineers should also check 12 mA and the manufacturer datasheet before releasing the final PCB, module, or power tree.
How should engineers review assembly risk for 74FCT2373CTSOCTG4?
Use the listed Small Outline Packages information together with 12 mA when checking PCB footprint, thermal clearance, solder process, and second-source constraints for at least 1 approved production build.
What should procurement confirm before ordering 74FCT2373CTSOCTG4?
Confirm lifecycle status, traceability, and lot availability, then compare the required 20-pin against the approved BOM so sourcing does not substitute an incompatible part during 1 purchasing cycle.
