74HC4316DB,118

Overview

The Nexperia 74HC4316DB,118 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 interfacing and provides logic level translation between 5 V digital logic and ±5 V analog signals.

Feature Summary

• Quad SPST analog switch architecture with individual channel control
• Logic level translation capability for mixed voltage environments
• Built-in break-before-make switching action
• Input clamp diodes for protection against voltages exceeding VCC

Applications

• Signal gating
• Modulation circuits
• Demodulation systems
• Chopper applications

Procurement Notes

Verify the specific ordering suffix '118' against official Nexperia documentation to confirm tape-and-reel packaging specifications. Confirm that the SO16 package variant matches the required PCB footprint and thermal dissipation requirements for the target application environment.

Selection Notes

Select this component when designing circuits requiring multiple isolated analog signal paths controlled by standard CMOS or TTL logic levels. Ensure the supply voltage differential meets the minimum threshold for acceptable ON resistance linearity, particularly if operating near 2.0 V where non-linearity increases.

Part Context

This part belongs to the 74HC/HCT family of high-speed CMOS logic devices manufactured by Nexperia. It serves as a fundamental building block for analog signal routing within digital systems, allowing microcontrollers or FPGAs to manage analog data streams without mechanical relays.

Replacement Considerations

Direct functional equivalents include the 74HCT4316 series for TTL-compatible logic interfaces. Verify pinout compatibility and electrical characteristics such as ON resistance and leakage current before substituting with other quad SPST analog switches.
