CD74FCT16374ATSM

Overview

The CD74FCT16374ATSM is a 16-bit D-type flip-flop from the FCT series, manufactured by Harris Corporation. It features true outputs with 3-state capability and operates within a supply voltage range of 2.7 V to 3.6 V, typically at 3.3 V. The device supports a maximum operating temperature of 85 °C and a minimum of -40 °C. It utilizes a TSSOP-48 plastic package with a propagation delay of 10 ns at nominal supply. The component includes bus hold inputs to eliminate external pull-up resistors and has a load capacitance specification of 50 pF.

Feature Summary

• 16-bit D-type flip-flop architecture with true output polarity
• Bus hold inputs integrated to remove requirement for external pull-up resistors
• 3-state output configuration for efficient bus line management
• CMOS construction compatible with standard logic families

Applications

• High-density digital data storage systems
• Parallel-to-serial data conversion interfaces
• Register banks in microprocessor-based architectures
• Timing control and synchronization circuits

Procurement Notes

Verify the manufacturer origin, as Harris Corporation assets were acquired by Renesas Electronics. Confirm the specific suffix ATSM corresponds to the required TSSOP-48 package and commercial temperature grade. Ensure compliance with RoHS directives if applicable, noting that older Harris documentation may indicate non-compliance status. Cross-reference the part number with current Renesas catalogs to confirm availability and updated specifications.

Selection Notes

Select this component when a high-speed 16-bit parallel register is required with minimal external circuitry. The integrated bus hold feature simplifies design by negating the need for pull-up components. Consider the 3-state output for multiplexed bus applications. Verify that the 3.3 V operating voltage aligns with the system power rails and that the TSSOP-48 package fits the PCB layout constraints.

Part Context

This device belongs to the FCT (Fast CMOS Technology) series, designed for high-speed operation with CMOS low power consumption. It serves as a critical interface element between parallel data buses and serial processing units or memory arrays. The 16-bit width allows for efficient handling of word-sized data in computing and communication systems.
