Overview
The SN74CB3Q3384ADGVR is a high-bandwidth FET bus switch manufactured by Texas Instruments. It utilizes a charge pump to elevate the gate voltage of the pass transistor, ensuring low and flat ON-state resistance. This device functions as a 10-bit registered buffer with level shifting capabilities. It operates within a supply voltage range of 2.5 V to 3.6 V. The component is housed in a 24-pin TVSOP package.
Feature Summary
- High-bandwidth FET bus switch architecture
- Integrated charge pump for low on-resistance
- Level shifting functionality
- Registered buffer configuration
Applications
- Portable equipment requiring level translation
- High-speed data bus switching
- Consumer electronics signal routing
Procurement Notes
Verify the specific suffix 'DGVR' corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the automotive-grade qualification aligns with your system's reliability standards. Ensure the operating temperature range meets your environmental specifications before finalizing the order.
Selection Notes
Select this component when low insertion loss and flat impedance are critical for signal integrity. The integrated charge pump allows for consistent performance across varying supply voltages. Consider the TVSOP package size if board space is limited. Verify compatibility with the target logic levels and switching speeds required by the application design.
Part Context
This part belongs to the SN74CB3Q series, which is designed for automotive applications. It shares functional similarities with other high-speed bus switches but includes specific automotive qualification features. The device is distinct from non-automotive variants by its enhanced reliability testing and long-term availability commitments typical of the Q-series.
Replacement Considerations
The SN74CB3Q3384ADBQR is a documented alternative offering identical pinout and functionality in a different package variant. Verify package dimensions and thermal characteristics when substituting.
