QS74FCT162373ATPA

Latches Overview

The QS74FCT162373ATPA is a dual 8-bit transparent latch belonging to the FCT logic series. It features true outputs and utilizes CMOS technology within a PDSO48 package. The device operates with two functional blocks, each handling eight bits of data across two ports. It supports a maximum output current of 0.024 A and is designed for a load capacitance of 50 pF. The component complies with RoHS standards and carries an EAR99 classification.

Latches Feature Summary

• Dual-function architecture providing independent control over two separate 8-bit data channels
• Transparent latch design suitable for temporary data storage applications
• CMOS construction ensuring low power consumption relative to legacy technologies

Latches Applications

• Memory address latching in digital systems
• I/O port buffering and interface management
• Bus driver implementations requiring high-speed data transfer

Latches Procurement Notes

Verify the manufacturer designation carefully, as Quality Semiconductor assets were acquired by Integrated Device Technology (IDT) and subsequently Renesas Electronics. Confirm that the specific suffix matches the required package variant and temperature range. Ensure compliance with current environmental regulations such as RoHS, noting that older stock may have different certification statuses compared to modern equivalents.

Latches Selection Notes

Select this component when a dual-channel 16-bit latch solution is required in a compact surface-mount format. Consider the balanced output drivers for noise reduction in high-speed environments. Evaluate the operating temperature range against system requirements, as industrial variants are available. Ensure the supply voltage aligns with standard 5V logic systems typical for the FCT family.

Latches Part Context

This part belongs to the 74FCT162373T series of fast CMOS transparent latches. Originally manufactured by Quality Semiconductor, production rights transferred to IDT and later Renesas. The series is characterized by high speed and low power, serving as a replacement for older ABT functions. It is distinct from bus transceivers like the 162245 due to its unidirectional latch functionality.

Latches Replacement Considerations

Public confirmed substitute part numbers include IDT74FCT162373ATPAG and 74FCT162373ATPAG.
