CD74HC4316PWT

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HC4316PWT is a high-speed CMOS quad analog switch manufactured by Texas Instruments, housed in a 16-pin TSSOP surface-mount package. It features four independent single-pole single-throw (SPST) switches with normally open configurations. The device operates on a single supply voltage ranging from 2V to 6V or dual supplies of ±1V to ±5V. Key electrical parameters include a maximum on-resistance of 170 ohms, a channel-to-channel matching of 5 ohms, and a bandwidth of 200MHz at -3dB. Switching times are specified with a maximum turn-on time of 37ns and turn-off time of 37ns. The component supports an operating temperature range from -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix PWT confirms the TSSOP-16 package variant during sourcing. Confirm RoHS compliance status as manufacturing updates may affect environmental declarations. Check for obsolescence notices or last-time buy notifications from the manufacturer. Ensure the supplier provides original packaging to maintain moisture sensitivity integrity. Validate that the component lot matches current production standards for reliability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST analog switch is required with high speed and wide bandwidth. Compare on-resistance specifications against load requirements to ensure signal integrity. Consider the TSSOP package dimensions for PCB layout constraints relative to alternative SOIC packages. Verify supply voltage ranges match the system design before integration. Evaluate thermal performance if operating near the upper temperature limit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the CD74HC4316 family of high-speed CMOS analog switches. It shares functional similarities with other members like the CD74HC4316M but differs in physical packaging. The TSSOP form factor offers a smaller footprint compared to standard SOIC versions. It is designed for applications requiring multiple isolated signal paths in dense circuit designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible alternatives include the CD74HC4316M in SOIC-16 packaging. Cross-reference electrical parameters such as Ron and bandwidth when substituting. Verify that any replacement maintains the same logic input voltage levels. Check for updated datasheets regarding changes in switching characteristics or package dimensions.
