DS1336

Overview

The DS1336 is an OR controller and source selector switch manufactured by Analog Devices Inc./Maxim Integrated. It features a 5:5 input-to-output ratio with internal switches, designed for battery backup and industrial applications. The device operates on a supply voltage ranging from 3V to 5.5V and draws a supply current of 250 µA. It supports a maximum output current of 300mA and has an open delay time of 100 ns. Available in 16-PDIP and 16-SOIC packages, it functions within a temperature range of 0°C to 70°C.

Feature Summary

• Functions as an OR controller and source selector switch for power path management
• Features five independent input channels switching to five corresponding outputs
• Supports high-current switching capability up to 300mA per channel

Applications

• Battery backup systems requiring seamless power source selection
• Industrial equipment needing redundant power path control
• Automotive grade applications utilizing robust switching architectures

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm package type availability, as the DS1336 exists in multiple form factors including PDIP and SOIC. Check specific suffixes for environmental compliance status. Ensure the selected variant matches the required operating temperature range for the intended application environment before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring centralized management of multiple power sources. The 5:5 configuration allows flexible redundancy schemes. Consider the 300mA output limit against load requirements. Evaluate the 100ns switching speed for transient response needs. Verify that the 3V to 5.5V supply range aligns with the system's available voltage rails and logic levels.

Part Context

The DS1336 belongs to Maxim Integrated’s portfolio of power management ICs focused on source selection. It complements other RTC and PMIC solutions by handling power integrity tasks. While distinct from the DS1337 real-time clock series, it shares manufacturing standards and interface compatibility within the broader Analog Devices ecosystem for embedded power control.

Replacement Considerations

The DS1336S serves as the surface-mount equivalent to the through-hole DS1336. Both share identical electrical specifications and pinout configurations. When replacing, ensure the PCB footprint accommodates the specific package variant chosen. No functional differences exist between the DIP and SOIC versions regarding switching performance.
