Overview
The SN74LV4052ADBR is a dual 4-channel analog multiplexer/demultiplexer from Texas Instruments, housed in a 16-SSOP package. It operates on a single supply voltage ranging from 1.65V to 5.5V. The device integrates two independent 4:1 analog switches controlled by common select inputs (A, B) and an enable pin (INH). Each channel supports bidirectional signal transmission with amplitudes up to 5.5V peak. Key electrical parameters include a nominal bandwidth of approximately 50 MHz, off-state isolation of about 45 dB, and a maximum on-resistance of 75 ohms. Propagation delays are typically 25 ns for both high-to-low and low-to-high transitions. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Dual independent 4:1 analog switching architecture with shared control logic
- Bidirectional signal transmission capability for both analog and digital signals
- Low on-resistance and low crosstalk characteristics for signal integrity
- High electrostatic discharge protection exceeding JESD 22 standards
Applications
- Signal gating and isolation in electronic circuits
- Data acquisition systems requiring analog signal routing
- Audio and video signal path selection
- Programmable logic interface circuits
Procurement Notes
Verify the specific ordering suffix 'DBR' corresponds to the 16-SSOP package and tape-and-reel shipping configuration as defined in the official datasheet. Confirm that the component meets RoHS compliance requirements if mandated by the design specification. Ensure the operating environment remains within the specified -40°C to +85°C industrial temperature range to maintain guaranteed performance parameters.
Selection Notes
Select this component when a compact solution for routing multiple analog or digital signals is required within a 1.65V to 5.5V system. The dual 4:1 configuration reduces board space compared to discrete switches. Consider the 75 ohm on-resistance limit for signal loss calculations. Verify that the 50 MHz bandwidth suffices for the highest frequency components of the signals being switched.
Part Context
This part belongs to the SN74LV4052A family of CMOS analog switches. It serves as a non-volatile memory-free alternative to mechanical relays for signal routing. The device complements other members like the SN74LV4051A (8-channel) and SN74LV4053A (triple 2-channel) within the same logic series, offering flexible topology options for complex switching matrices.
Replacement Considerations
Direct functional equivalents include the SN74LV4052APWR in TSSOP-16 packaging. For automotive applications, verify compatibility with the AEC-Q100 qualified SN74LV4052A-Q1 variant. Cross-reference pinouts and electrical specifications carefully before substitution.
