74FCT163373CPAG8

Latches Overview

The Renesas 74FCT163373CPAG8 is a 16-bit high-speed, low-power transparent D-type latch housed in a 48-pin TSSOP package. It operates within a supply voltage range of 2.3V to 3.6V and supports a working temperature range of -40°C to +85°C. The device features two independent 8-bit channels with tri-state outputs capable of sourcing 8mA and sinking 24mA. Propagation delay is typically 1.5ns.

Latches Feature Summary

• Transparent data storage architecture suitable for temporary data holding
• Mixed-voltage input compatibility allowing driving from both 3.3V and 5V logic sources
• Rail-to-rail output swing characteristics providing increased noise margin
• Low ground bounce performance ensuring signal integrity during switching

Latches Applications

• Memory address latching systems
• I/O port buffering interfaces
• Bus driver implementations in mixed voltage environments

Latches Procurement Notes

This component is officially designated as obsolete by the manufacturer. Product discontinuance notifications confirm end-of-life status. Verification of current availability requires checking authorized distributors for remaining stock or evaluating approved replacement components. Ensure final design-in decisions account for long-term supply constraints associated with discontinued logic families.

Latches Selection Notes

Select this part for applications requiring 16-bit latching with mixed 3.3V/5V interface capabilities. Verify that the 48-TSSOP footprint matches the PCB layout. Confirm that the 2.3V to 3.6V operating range aligns with the system power rails. Consider the obsolete status when planning for future production runs and potential need for redesign.

Latches Part Context

Part of the 74FCT series, which combines CMOS low power consumption with TTL-compatible speeds. The 74FCT163373 variant specifically provides dual 8-bit or single 16-bit latch functionality. The CPAG8 suffix indicates the specific tape-and-reel packaging configuration and RoHS compliance status for this Renesas product line.

Latches Replacement Considerations

Consult official Renesas documentation for confirmed substitute part numbers. Evaluate alternative FCT-series latches with compatible pinouts and electrical specifications. Verify that any replacement maintains the required 48-pin TSSOP package and mixed-voltage input tolerance.
