Overview
The SN74AHC2G53HDCU3 is a single-channel analog switch configured as a single-pole double-throw (SPDT) circuit or 2:1 multiplexer/demultiplexer. Manufactured by Texas Instruments, it operates on a single supply voltage ranging from 1.65 V to 5.5 V. The device features a maximum on-resistance of 13 ohms and supports a switching current of 100 mA. It is housed in an 8-VFSOP package with dimensions of 0.091 inches (2.30 mm) width. The component functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Supports bidirectional analog signal switching with low on-resistance for minimal signal attenuation.
- Operates across a wide single-supply voltage range compatible with standard logic families.
- Provides high bandwidth performance suitable for high-speed data routing applications.
Applications
- Portable equipment requiring low power consumption and small form factor
- Battery-powered systems utilizing single-supply operation
- Automotive infotainment and instrument cluster signal routing
Procurement Notes
Verify the specific suffix HDCU3 corresponds to the 8-VFSOP package and tape-and-reel or cut-tape availability as required by your assembly process. Confirm RoHS compliance status and moisture sensitivity level (MSL 1) prior to soldering. Ensure the ordering quantity matches the manufacturer's standard packaging units to avoid partial reel handling issues during procurement.
Selection Notes
Select this component when a single SPDT analog switch is required within the 1.65 V to 5.5 V supply range. It is appropriate for designs needing 13 ohm on-resistance and 100 mA continuous current capability. Consider the 8-VFSOP package constraints for PCB layout. Compare against SN74LVC2G53 variants if higher voltage tolerance or different speed characteristics are needed for the specific application environment.
Part Context
This part belongs to the SN74AHC2G53 family of dual-gate analog switches. It shares functional similarities with the SN74LVC2G53 and SN74AUC2G53 series but differs in supply voltage ranges and switching speeds. The AHC series typically offers balanced performance between speed and power consumption compared to the LVC and AUC counterparts.
Replacement Considerations
Direct substitutes include SN74LVC2G53DCTR and SN74AUC2G53DCUR. Verify pin compatibility and electrical parameter differences such as on-resistance and propagation delay before substitution. Package variations may require PCB footprint adjustments.
