74ABT16374CSSC

Flip Flops Overview

The Fairchild Semiconductor 74ABT16374CSSC is a discontinued high-speed CMOS D-type flip-flop. It contains two independent 8-bit registers with positive-edge triggering and three-state outputs, housed in a 48-SSOP package. The device operates within a 4.5V to 5.5V supply range and supports a maximum clock frequency of 150 MHz. Key electrical specifications include a maximum propagation delay of 6.2ns at 5V with 50pF load, output drive currents of 32mA (high) and 64mA (low), and a static current consumption of 2 mA. It functions across an industrial temperature range of -40°C to +85°C.

Flip Flops Procurement Notes

This component is officially obsolete and no longer manufactured by onsemi. Verification of availability is restricted to existing stock from distributors or surplus suppliers. Cross-reference replacement part numbers such as SN74ABT16374ADGGR or CY74FCT16374CTPVC should be evaluated against original datasheet parameters to ensure functional compatibility. Direct procurement from the manufacturer is not possible.

Flip Flops Selection Notes

Designers requiring this specific logic family must account for the discontinuation status when planning long-term production. Selection should prioritize verified substitute components that match the 48-pin SSOP footprint and 150 MHz speed requirements. Electrical parameters including voltage ranges and output drive capabilities must be compared against alternative parts to maintain system integrity without redesigning the board layout.

Flip Flops Part Context

The 74ABT16374 belongs to the ABT logic series, designed for high-speed applications using advanced bipolar-CMOS technology. This specific model integrates two octal D-type flip-flops into a single package, providing efficient space utilization for complex digital circuits. The CSSC suffix denotes the specific 48-SSOP packaging variant suitable for surface-mount assembly processes.

Flip Flops Replacement Considerations

Public confirmed substitutes include SN74ABT16374ADGGR and CY74FCT16374CTPVC. These alternatives offer similar functionality but may differ in pinout or electrical characteristics. Verify package dimensions and signal compatibility before integration.
