Overview
The SN74AUC2G53DCUR is a single-pole, double-throw (SPDT) analog switch or 2:1 analog multiplexer/demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 0.8 V to 2.7 V and supports surface-mount installation in an 8-VSSOP package. Key electrical parameters include a maximum on-resistance of 15 ohms, a channel-to-channel matching of 1 ohm maximum, and a leakage current of 1 µA maximum. The device features a -3dB bandwidth of 500 MHz, with turn-on and turn-off times of 2.2 ns and 2.3 ns respectively. It functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Provides SPDT switching or 2:1 multiplexing functionality for signal routing applications
- Supports low-voltage operation down to 0.8 V for energy-efficient designs
- Features low on-resistance and tight channel matching for signal integrity
Applications
- Portable equipment requiring low-power signal switching
- Battery-powered systems utilizing low-voltage logic levels
- Consumer electronics needing compact analog signal routing
Procurement Notes
Verify the specific ordering suffix DCUR corresponds to the VSSOP-8 package and reel packaging configuration required for your assembly process. Confirm that the component meets RoHS3 compliance standards if mandated by your manufacturing specifications. Ensure the voltage rating aligns with your system's power supply constraints before procurement.
Selection Notes
Select this component when a single SPDT switch or 2:1 mux is needed in a minimal footprint. It is suitable for applications requiring sub-2.7 V operation where low capacitance and high bandwidth are critical. Compare against LVC series variants if higher voltage tolerance is required, noting the AUC series offers superior speed at lower voltages.
Part Context
This part belongs to the SN74AUC2Gxx family of ultra-low voltage analog switches. It shares functional similarities with other devices in the series but is distinguished by its specific SPDT configuration and 8-pin VSSOP packaging. It serves as a compact solution for signal path management in space-constrained portable devices.
Replacement Considerations
The SN74LVC2G53DCUR is a related variant offering similar functionality but with a higher voltage range of 1.65 V to 5.5 V. Verify compatibility if your design requires operation above 2.7 V or utilizes different logic levels.
