Overview
The CD74HCT4316M is a high-speed CMOS quad analog switch manufactured by Harris Corporation. It integrates four independent single-pole single-throw (SPST) normally-open switches within a 16-pin SOIC package. The device operates with a single supply voltage range of 4.5V to 5.5V, ensuring compatibility with standard HCT logic levels. Key electrical characteristics include a maximum on-resistance of 170 ohms and a channel-to-channel matching of 5 ohms. The component supports a -3dB bandwidth of 200MHz with switch times of 37ns. It functions reliably across an extended industrial temperature range from -55°C to +125°C.
Feature Summary
- Integrates four independent SPST analog switches in a compact surface-mount package
- Provides high-speed signal switching with 200MHz bandwidth capability
- Ensures signal integrity through low on-resistance and tight channel matching
Applications
- Signal routing in data acquisition systems
- Multiplexing audio or video signals
- Test and measurement equipment input selection
Procurement Notes
Verify the manufacturer designation carefully, as Texas Instruments acquired Harris Semiconductor's logic products. Confirm that the specific part number corresponds to the original Harris production run rather than subsequent TI manufacturing. Check for RoHS compliance status, as older Harris parts may differ from current TI equivalents. Ensure the package type matches the required PCB footprint.
Selection Notes
Select this component when HCT logic level compatibility is required for control inputs. The 4.5V to 5.5V supply range distinguishes it from HC variants which support wider voltages. Consider the 170-ohm on-resistance limit for signal loss calculations. Verify thermal requirements against the -55°C to +125°C operating range for harsh environments.
Part Context
This component belongs to the 74HCT series of high-speed CMOS logic devices originally produced by Harris Corporation. The series was designed to bridge TTL and CMOS logic families, offering noise immunity and low power consumption. Harris Corporation was a significant semiconductor manufacturer before its logic division was acquired by Texas Instruments, which continues to produce similar devices under updated part numbers.
Replacement Considerations
Texas Instruments CD74HC4316M96 serves as a primary replacement. Verify pinout compatibility and ensure the HCT input thresholds are maintained if replacing with HC variants.
