74FCT2373CTSOCTE4

Latches Overview

The Texas Instruments 74FCT2373CTSOCTE4 is an octal transparent D-type latch featuring three-state outputs, housed in a 20-pin SOIC package. It operates within a supply voltage range of 4.75V to 5.25V and supports an industrial temperature range from -40°C to +85°C. The device provides high-drive capabilities with output currents up to 64mA and includes low-impedance drivers designed for bus-oriented applications.

Latches Feature Summary

• Octal transparent D-type latch architecture with three-state outputs
• High-drive capability supporting up to two CMOS loads or one LSTTL load per output
• Low-impedance driver design suitable for distributed buffering

Latches Applications

• Bus-oriented memory mapping
• I/O port buffering
• Clock buffering and driving

Latches Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance as per manufacturer standards. Confirm the 'C' prefix denotes commercial temperature grade (-40°C to +85°C) and the 'SOCT' suffix specifies the 20-pin SOIC tube packaging. Ensure compatibility with existing 5V logic systems before procurement.

Latches Selection Notes

Select this component for designs requiring octal data latching with high drive strength in a compact surface-mount format. It serves as a direct replacement for standard 74FCT373 equivalents. Consider the three-state feature for bidirectional bus control where output enable/disable functionality is required.

Latches Part Context

This part belongs to the FCT (Fast CMOS Technology) family, bridging the performance gap between standard TTL and CMOS logic. It offers speed comparable to LS-TTL with CMOS power consumption. The 74FCT2373 variant specifically provides transparent latching behavior, distinct from edge-triggered flip-flops like the 74FCT573.

Latches Replacement Considerations

Publicly confirmed substitute part numbers include SN74FCT2373DT and SN74FCT2373DWR. Verify pinout compatibility and electrical specifications against original datasheets before substitution.
