74HC4316DB,112

Overview

The Nexperia 74HC4316DB,112 is a quad single-pole single-throw (SPST) analog switch housed in an SO16 plastic small outline package. It features four independent switches with active HIGH enable inputs and an active LOW global enable input. The device supports dual-supply operation with VCC ranging from 2.0 V to 10.0 V and VEE from -10.0 V to 0 V. Typical ON resistance values are 160 Ω at 4.5 V supply difference, 120 Ω at 6.0 V, and 80 Ω at 9.0 V. It includes clamp diodes for overvoltage tolerance and provides logic level translation between 5 V digital signals and ±5 V analog domains.

Feature Summary

• Quad SPST analog switching architecture with individual channel control
• Dual-supply capability enabling interface between 5 V logic and bipolar analog signals
• Built-in break-before-make timing to prevent signal shorting during switching
• Input clamp diodes allowing safe interfacing with voltages exceeding the positive supply rail

Applications

• Signal gating in data acquisition systems
• Modulation and demodulation circuits
• Chopper stabilization amplifiers

Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and temperature range. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure the selected variant matches the required SO16 package dimensions and lead form factor for PCB integration.

Selection Notes

Select this component when designing circuits requiring isolation of multiple analog channels controlled by standard CMOS logic levels. Verify that the required ON resistance and leakage currents meet system specifications at the intended operating voltage differential. Consider thermal derating requirements if driving significant load currents through the switches.

Part Context

This part belongs to the 74HC/HCT family of high-speed CMOS logic devices manufactured by Nexperia. It serves as a specialized analog interface within the broader portfolio of logic ICs, bridging digital control domains with analog signal paths. The device complements other multiplexers and switches in the lineup for complex signal routing applications.

Replacement Considerations

Direct functional equivalents include the 74HCT4316 variants for TTL-compatible logic levels. Alternative packages such as TSSOP16 (74HC4316PW) offer pin-compatible physical replacements. Cross-reference with other quad SPST analog switches if different ON resistance characteristics are required.
