Frequently Asked Questions
What is the CD74HC173NSRG4 and what type of flip-flop does it use?
The CD74HC173NSRG4 is a Quad D-Type Flip-Flop with 3-state outputs and dual output enable from Texas Instruments. It stores 4 bits of data using D-type flip-flop cells and is part of the HC CMOS logic family, offering high-speed operation with 50 pF load capacitance.
What are the dual output enable pins used for on the CD74HC173NSRG4?
The dual output enable inputs (OE1 and OE2) on the CD74HC173NSRG4 control when the 3-state outputs are active or in high-impedance mode. Both enables must be asserted simultaneously to drive the outputs, providing flexible bus control and allowing multiple registers to share a common data bus without contention.
What is the output drive capability and load capacitance of the CD74HC173NSRG4?
The CD74HC173NSRG4 provides a maximum output low current (I(ol)) of 6 mA and is rated for a 50 pF load capacitance. These parameters ensure reliable operation when driving typical PCB trace capacitances and other logic inputs in digital bus systems.
What package does the CD74HC173NSRG4 come in?
The CD74HC173NSRG4 is available in a 16-pin SOIC (Small Outline Integrated Circuit) package, as indicated by JESD-30 Code R-PDSO-G16. This surface-mount package is compatible with automated PCB assembly and supports compact board layouts.
What are typical applications for the CD74HC173NSRG4?
Typical applications include data bus registers, pipeline storage, I/O port latches, and interface buffers in microprocessor and embedded systems. The tri-state outputs and dual output enables make it particularly useful in multi-master bus architectures where multiple devices share a bidirectional data bus.
