Frequently Asked Questions
What is the SN74CBT3384CDBQRG4 and what is it used for?
The SN74CBT3384CDBQRG4 is a 10-bit CMOS bus switch IC from Texas Instruments. It is designed for high-speed bus connectivity applications, allowing signals to pass between two buses with near-zero propagation delay. It features active-low output enable control, 3-state outputs, and a typical on-resistance of 5 Ω, making it ideal for data buses in computing, networking, and telecommunications equipment.
What package does the SN74CBT3384CDBQRG4 use and how many pins does it have?
The SN74CBT3384CDBQRG4 is housed in a 24-pin SSOP (Shrink Small Outline Package). This compact surface-mount package is suitable for space-constrained PCB designs while providing reliable electrical connections for high-speed bus switching applications.
What is the typical on-resistance of the SN74CBT3384CDBQRG4?
The SN74CBT3384CDBQRG4 has a typical on-resistance of approximately 5 Ω. This low on-resistance minimizes signal attenuation and voltage drop across the switch, ensuring signal integrity when the device is enabled. This characteristic makes it well-suited for high-speed data bus applications where signal quality is critical.
How is the SN74CBT3384CDBQRG4 controlled?
The SN74CBT3384CDBQRG4 uses active-low enable control, meaning the bus switch is activated when the enable pin is driven low. When the enable pin is high, the outputs are placed in a high-impedance (3-state) condition, effectively disconnecting the bus. This unidirectional control allows system designers to selectively connect or isolate bus segments as needed.
Is the SN74CBT3384CDBQRG4 RoHS compliant?
Yes, the SN74CBT3384CDBQRG4 is RoHS compliant as indicated by its JESD-609 code e4, which denotes a lead-free (Pb-free) device. The 'G4' suffix in the part number also confirms that this device meets RoHS environmental regulations, making it suitable for use in environmentally conscious designs and products sold in markets with strict hazardous substance restrictions.
