Overview
The MC74HC4053ADT is a triple single-pole double-throw (SPDT) analog multiplexer/demultiplexer manufactured by onsemi. It utilizes silicon-gate CMOS technology to provide fast switching speeds and low ON resistance. The device features three independent switches, each with two selectable channels plus a common off state. It operates with an analog power supply range of 2.0 V to 12.0 V (VCC – VEE) and a digital control supply range of 2.0 V to 6.0 V. Key electrical parameters include a maximum ON resistance of 190 Ω at VCC=4.5 V and 100 Ω at VCC=6.0 V, with a maximum OFF leakage current of 1.0 μA. The component is housed in a TSSOP-16 package.
Feature Summary
- Triple SPDT configuration allowing independent control of three separate analog signal paths
- Silicon-gate CMOS construction ensuring improved linearity and lower ON resistance compared to metal-gate counterparts
- Diode protection integrated on all inputs and outputs to guard against high static voltages
- Compatible with standard CMOS logic levels for channel select and enable functions
Applications
- Signal routing in data acquisition systems
- Audio and video signal switching applications
- Instrumentation front-end multiplexing
- Analog signal conditioning circuits
Procurement Notes
Verify the ordering suffix 'DT' corresponds to the TSSOP-16 package variant when sourcing. Confirm that the specific revision of the datasheet matches the production batch requirements. Ensure that the analog voltage swings remain within the specified VCC and VEE limits to prevent damage. Check for RoHS compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select this component when three independent dual-channel analog switches are required in a compact surface-mount package. Compare the ON resistance specifications against the load requirements to ensure signal integrity. Verify that the propagation delay characteristics meet the timing constraints of the application. Consider the operating temperature range of -55°C to +125°C for industrial or automotive environments.
Part Context
This part belongs to the MC74HC405xA family, which includes the MC74HC4051A (8-channel) and MC74HC4052A (dual 4-channel). All devices share similar pinout compatibility with the older MC1405xAB metal-gate series but offer enhanced performance through CMOS technology. The ADT suffix specifically denotes the TSSOP-16 thin-shrink small-outline package.
Replacement Considerations
Direct pin-compatible replacements include other manufacturers' versions of the 74HC4053. Verify that substitute parts maintain the same TSSOP-16 footprint and electrical characteristics, particularly ON resistance and leakage currents, to ensure circuit functionality remains unchanged.
