CD74FCT162373TSM

Latches Overview

The CD74FCT162373TSM is a 16-bit transparent D-type latch manufactured by Harris Corporation, belonging to the FCT series. It utilizes CMOS technology and features two functional blocks of 8 bits each with true outputs. The device operates within an industrial temperature range of -40°C to 85°C and supports a supply voltage typically centered at 5V. It is housed in a 48-pin SSOP package (SSOP48,.4) and includes bus hold inputs to eliminate external pull-up resistors.

Latches Feature Summary

• Bus hold inputs integrated to remove the need for external pull-up resistors
• Three-state outputs equipped with series resistors
• Transparent D-type latch architecture for temporary data storage

Latches Applications

• Memory address latching
• I/O port implementation
• Bus driver applications

Latches Procurement Notes

Verify component authenticity as this part may be obsolete or from legacy inventory. Confirm package marking matches the SSOP48 specification. Check RoHS compliance status, as original Harris versions are often non-compliant. Ensure the specific suffix 'TSM' corresponds to the correct tape-and-reel or tube packaging variant required for your assembly process.

Latches Selection Notes

Select this component when a high-speed, low-power 16-bit latch is required for systems compatible with the FCT logic family. It serves as a replacement for older ABT functions. Verify that the 50 pF load capacitance rating meets system requirements. Ensure the design accommodates the specific pinout of the 48-pin SSOP package.

Latches Part Context

This device is part of the Harris FCT (Fast CMOS) line, designed to offer high-speed performance with low power consumption. It is functionally similar to other 16-bit latches like the IDT74FCT162373 series but differs in manufacturer-specific characteristics and packaging options such as the SSOP form factor.

Latches Replacement Considerations

IDT74FCT162373ATPAG is a documented equivalent offering similar functionality in a TSSOP-48 package. Verify pin compatibility and electrical specifications before substitution.
