74ABT16374CSSCX

Flip Flops Overview

The Fairchild Semiconductor 74ABT16374CSSCX is a dual-element D-type flip-flop logic integrated circuit. It features two independent eight-bit registers with positive-edge triggering and three-state outputs. The device operates within a supply voltage range of 4.5V to 5.5V, supporting a maximum clock frequency of 150 MHz. It utilizes a 48-pin BSSOP package with dimensions of 7.50mm width. Key electrical characteristics include a maximum propagation delay of 6.2ns at 5V with 50pF load capacitance, high output drive currents of 32mA (high) and 64mA (low), and a static current consumption of 2 mA.

Flip Flops Feature Summary

• Dual eight-bit D-type flip-flop architecture with positive-edge clock triggering
• Three-state non-inverting outputs for bus-oriented applications
• High-speed operation supporting up to 150 MHz clock frequencies
• Low input capacitance of 5 pF for reduced signal loading

Flip Flops Applications

• Bus driver circuits requiring byte-controlled data storage
• High-speed parallel data transfer interfaces
• System memory buffering and register stages
• Clock distribution networks in digital systems

Flip Flops Procurement Notes

Verify the specific manufacturer designation and package marking against official datasheets to confirm authenticity. Ensure the component matches the required 48-BSSOP form factor and electrical specifications for the target application. Cross-reference part numbers carefully as obsolete status may affect availability and sourcing channels.

Flip Flops Selection Notes

Select this component for designs requiring dual-byte latching with high-speed performance and three-state output control. Consider the 4.5V to 5.5V operating range and 6.2ns propagation delay when timing constraints are critical. Evaluate the 48-pin surface mount package suitability for PCB layout density and thermal requirements.

Flip Flops Part Context

This part belongs to the 74ABT series of advanced BiCMOS logic devices, designed for high-speed and low-power applications. It is functionally compatible with other 74ABT16374 variants but differs in packaging and manufacturing origin. The device serves as a standard solution for 16-bit data handling in complex digital logic systems.
