CD74FCT16373TSM

Latches Overview

The CD74FCT16373TSM is a dual 8-bit transparent latch belonging to the FCT logic series, manufactured by Harris Corporation. It features true outputs and is housed in a PDSO48 package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a wide operating temperature range from -40 °C to +85 °C. Designed for high-speed applications, it utilizes CMOS technology to provide efficient signal latching with low power consumption characteristics typical of the FCT family.

Latches Feature Summary

• Dual 8-bit configuration providing independent latching for two sets of data lines
• Transparent latch operation allowing direct data passage when enabled
• True output polarity maintaining input signal state at the output pins
• Bus hold inputs designed to eliminate the need for external pull-up resistors

Latches Applications

• High-speed data bus buffering and storage
• Parallel interface data latching systems
• Memory address register implementations
• Digital signal processing data path control

Latches Procurement Notes

Verify manufacturer authenticity as Harris Corporation has undergone corporate restructuring and acquisitions. Confirm specific lot codes against current Intersil or Renesas documentation if applicable. Ensure RoHS compliance status matches project requirements, noting that older Harris batches may differ from modern equivalents. Validate package marking accuracy to distinguish between original Harris production and subsequent rebranded inventory.

Latches Selection Notes

Select this component for designs requiring dual-channel 8-bit latching with true output polarity. The FCT series offers speed-performance comparable to LS-TTL while maintaining CMOS power efficiency. Consider the PDSO48 package dimensions for PCB layout constraints. Verify that the 4.5 V to 5.5 V supply range aligns with the system's voltage rails before finalizing the bill of materials.

Latches Part Context

This part belongs to the Harris FCT (Fast CMOS Technology) line, which bridges the performance gap between standard TTL and advanced CMOS logic families. Harris Corporation was a prominent semiconductor manufacturer before its acquisition by Intersil, which later merged with Renesas Electronics. The CD74 prefix indicates commercial grade temperature rating within the broader 74xx logic nomenclature.

Latches Replacement Considerations

Cross-reference with IDT74FCT16373 or Renesas equivalents for pin-compatible replacements. Verify electrical specifications match exactly, particularly propagation delay and output drive strength. Check for any packaging suffix differences that might indicate variant lead finishes or moisture sensitivity levels.
