PT8A2516NE

Programmable Timers And Oscillators Overview

The PT8A2516NE is a CMOS LSI simple timer IC manufactured by Diodes Incorporated (formerly Pericom). It operates within a supply voltage range of 3.5V to 5.5V and features an adjustable timer duration from 20 minutes to 16 hours, determined by external R/C components. The device integrates a power-on reset circuit, logic control, key scan, and output driver. It provides a high-active relay output capable of sourcing up to 10mA or sinking up to 100µA. The chip supports both internal and external oscillators, with the latter utilizing an R/C network for frequency generation.

Programmable Timers And Oscillators Procurement Notes

Verify package configuration upon receipt; the NE suffix indicates a lead-free TO94-4L package. Confirm component authenticity through authorized distribution channels. Ensure storage conditions remain within -40°C to +125°C to maintain reliability. Check datasheet specifications against specific application requirements before integration.

Programmable Timers And Oscillators Selection Notes

Select this component when a low-cost, single-chip solution for relay timing is required. The PT8A2516NE is suitable for designs needing a 3.5V to 5.5V supply. Consider the SOT23-5L variant if surface-mount assembly is preferred over the through-hole TO94-4L package. External R/C values must be selected to achieve the desired timer interval within the specified frequency limits.

Programmable Timers And Oscillators Part Context

The PT8A2516NE belongs to the PT8A2516 series of simple timers. It is functionally similar to the PT8A2515 but may differ in specific pin configurations or internal logic implementations as indicated by the part number differentiation. Both are available in TO94-4L and SOT23-5L packages.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include other parts from the PT8A2516 series, such as the PT8A2515, provided pin compatibility and functional requirements match. Verify package type (TO94-4L vs. SOT23-5L) when substituting.
