• Interactive voice response units

Procurement Notes

Verify the part status as obsolete before procurement planning. Confirm that the 28-DIP through-hole package aligns with existing board layouts. Ensure the 2.4 V to 5.5 V operating range matches the system power design. Validate the SPI or pushbutton interface requirements against the host controller capabilities.

Selection Notes

Select this component when long-duration voice storage up to 360 seconds is required. Consider the through-hole packaging constraint for mechanical stability needs. Evaluate the analog single-ended input compatibility with existing microphone or line-level sources. Assess the need for direct pushbutton operation versus digital SPI control integration.
