Overview
The SN74AUC2G53DCTR 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 an operating temperature range from -40°C to +85°C. The device features a maximum on-resistance of 15 ohms, a channel-to-channel matching of 1 ohm, and a bandwidth of 500 MHz. Switching times are specified at 2.2 ns for turn-on and 2.3 ns for turn-off. Leakage current is limited to 1 µA, with capacitance values of 3 pF and 4.5 pF. It is housed in an 8-VSSOP package.
Feature Summary
- Provides SPDT switching or 2:1 multiplexing functionality within a compact surface-mount package.
- Operates effectively across a low-voltage range starting from 0.8 V up to 2.7 V.
- Maintains high signal integrity through low on-resistance and minimal channel-to-channel variation.
Applications
- Signal routing in portable battery-powered electronic devices
- Data acquisition systems requiring low-voltage analog switching
- Multiplexing applications in communication equipment
Procurement Notes
Verify the specific suffix DCTR against official Texas Instruments documentation to confirm the tape-and-reel packaging configuration. Ensure the component meets RoHS3 compliance standards as indicated in public records. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.
Selection Notes
Select this component when designing circuits that require low-voltage operation below 3.3 V. The 8-VSSOP package is suitable for space-constrained layouts. Verify that the required signal bandwidth does not exceed 500 MHz and that the leakage current specifications align with the application's sensitivity requirements.
Part Context
This component belongs to the SN74AUC2G series, which utilizes advanced CMOS technology for low-power consumption. The AUC logic family is designed for high-speed performance while maintaining low supply voltages. This specific model integrates analog switching capabilities alongside digital control signals within a dual-gate format.
Replacement Considerations
Publicly documented substitutes include SN74AUC2G53DCUR and SN74AUC2G53YZPR. These variants share identical electrical characteristics but differ in packaging types such as VSSOP or DSBGA. Verify pinout compatibility and thermal performance before implementing any substitution.
