QS74FCT162373ATPV

Latches Overview

The QS74FCT162373ATPV is a dual 8-bit transparent latch manufactured by Quality Semiconductor, housed in a 48-pin SSOP surface-mount package. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of -40°C to 85°C. The device features tri-state outputs with high drive capabilities, specified at 115mA for high state and 24mA for low state. Propagation delay is typically 2ns. This component belongs to the 74FCT logic series and is currently classified as obsolete.

Latches Feature Summary

• Dual-channel architecture providing two independent 8-bit transparent latches within a single integrated circuit.
• Tri-state output configuration enabling effective bus driving and system isolation.
• High-current output drive capability designed for robust signal transmission in digital systems.

Latches Applications

• Parallel data storage in high-speed digital processing units
• Bus interface buffering for system interconnects
• Transparent latch applications requiring fast propagation delays

Latches Procurement Notes

This component is officially listed as obsolete and no longer manufactured. Verification of availability should focus on surplus or secondary market sources rather than direct distributor stock. Confirm the specific manufacturer origin, as this part number was also produced by other entities such as Texas Instruments and Quality Semiconductor under similar designations. Ensure compatibility with existing board layouts before sourcing from alternative suppliers.

Latches Selection Notes

Select this component only if legacy support for the 74FCT series is required and pin-compatible alternatives are unavailable. Verify that the 48-SSOP package dimensions match the target PCB footprint. Consider the high output current specifications when designing load requirements. Evaluate end-of-life status implications for long-term production viability and potential need for redesign.

Latches Part Context

The 74FCT162373 family represents high-speed CMOS logic devices widely used in parallel data handling applications. Produced by multiple vendors including Integrated Device Technology (IDT), Renesas, and Quality Semiconductor, these parts share functional similarities but may vary in specific electrical characteristics or packaging details. The QS variant specifically denotes the Quality Semiconductor manufacturing source.

Latches Replacement Considerations

Publicly confirmed substitute part numbers include SN74ALVCH162373LR from Texas Instruments. Other cross-manufactured equivalents exist under different prefixes such as CY74FCT162373ATPVC or IDT74FCT162373ETPAG, though these represent different manufacturers rather than direct drop-in replacements without verification.
