MM74HC4316N

Overview

The MM74HC4316N is a quad analog switch implemented in silicon-gate CMOS technology, housed in a 16-lead Plastic Dual-In-Line (PDIP) package. It features three supply pins to support a level translator, enabling operation with 0–6V logic levels and up to ±6V analog switch levels. The device provides bidirectional switching with low ON resistance and low OFF leakage. Key electrical parameters include a typical ON resistance of 50 Ω at VCC−VEE = 4.5V and 30 Ω at 9V. Maximum quiescent current is 80 µA. The operating temperature range extends from -55°C to +125°C.

Feature Summary

• Integrated level translator allowing compatibility between standard logic voltages and higher analog signal swings.
• Bidirectional signal path capability where any analog input may function as an output.
• Includes both individual switch control inputs and a common enable input for system-level management.

Applications

• Analog signal routing in multiplexing systems
• Signal gating applications requiring voltage translation
• Data acquisition systems interfacing different voltage domains

Procurement Notes

Verify the specific ordering suffix to confirm the package type, as the MM74HC4316 series includes SOIC, SOP, TSSOP, and PDIP variants. Ensure the selected part matches the required thermal and mechanical constraints for the target PCB layout. Confirm that the manufacturer documentation aligns with the requested component specifications before finalizing procurement orders.

Selection Notes

Select this component when bidirectional switching with integrated level translation is required. The wide analog input voltage range supports signals up to ±6V. Consider the maximum ON resistance limits under worst-case temperature conditions during design. Verify that the control logic levels match the available supply voltages to ensure reliable switching performance across the full operating temperature range.

Part Context

This component belongs to the 74HC family of high-speed CMOS logic devices. It serves as a specialized analog switch variant within this lineage, distinguished by its ability to handle analog signals while translating digital control levels. The N suffix specifically denotes the 16-lead PDIP package format, distinguishing it from surface-mount alternatives like the M or MTC suffixes.

Replacement Considerations

The CD74HC4316M96 is a documented substitute offering similar quad analog switch functionality. Verify pinout compatibility and electrical characteristics against the original datasheet before implementation. Ensure the replacement package type meets the physical mounting requirements of the existing design.
