PT8A2513NEX

Programmable Timers And Oscillators Overview

The PT8A2513NEX is a CMOS LSI universal timer designed for simple timing control applications. It operates within a supply voltage range of 3.5V to 5.5V and requires minimal external components. The device features an integrated oscillator circuit controlled by external RC elements, with a typical frequency of 1024 Hz at VCC = 4.0V. It provides a high-active relay control output capable of sourcing up to 12 mA or sinking 0.5 mA. Current consumption is typically under 100 µA at 4.0V. The component is housed in a 4-pin TO-94 package.

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix 'X' against the manufacturer's official documentation to confirm if it denotes tape-and-reel packaging or other handling variations. Ensure the source document explicitly defines the suffix meaning before procurement planning.

Programmable Timers And Oscillators Selection Notes

Select this component for low-cost timing applications requiring a single-channel relay output. Verify that the external RC network connected to the OSC pin can achieve the desired timing interval based on the internal oscillator frequency. Ensure the load connected to the RELAY pin does not exceed the 20mA absolute maximum rating.

Programmable Timers And Oscillators Part Context

The PT8A2513NE is part of a series of simple universal timers manufactured by Pericom Technology (now Diodes Incorporated). These chips are designed as cost-effective solutions for basic time-delay functions in household appliances, replacing more complex discrete logic or microcontroller-based timing circuits.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements must match the 4-pin TO-94 package and provide similar relay drive capabilities. Check datasheets for compatible parts offering identical pinouts and operating voltage ranges to ensure mechanical and electrical interchangeability.
