NJU3715G

Serializers, Deserializers Overview

The NJU3715G is a 16-bit serial to parallel converter designed for MPU outport expansion. It utilizes CMOS technology and operates at a supply voltage of 4.5V to 5.5V with a maximum operating frequency of 5MHz. The device features a shift register and latch circuit, converting serial data into parallel outputs via P1 through P16 terminals. It includes hysteresis input circuits for noise immunity and high-drive output buffers capable of sourcing or sinking up to 25mA per pin. The component supports clear, strobe, clock, and data inputs, functioning within an operating temperature range of -25°C to +85°C.

Serializers, Deserializers Procurement Notes

Verify the specific package variant, as the G suffix corresponds to the SDIP22 outline. Confirm end-of-life status and lead times directly with Nisshinbo Micro Devices or authorized distributors, as availability may be restricted. Ensure the design accommodates the 4.5V to 5.5V supply requirement and thermal dissipation limits for the chosen package.

Serializers, Deserializers Selection Notes

Select this component when a 16-bit expansion is required for microprocessor interfaces. Consider the SDIP22 package for through-hole mounting requirements. Verify that the 25mA output current per pin meets the load specifications. Ensure the system operates within the 4.5V to 5.5V voltage range and that the 5MHz clock speed aligns with the processor's timing constraints.

Serializers, Deserializers Part Context

The NJU3715 series belongs to Nisshinbo Micro Devices' logic IC portfolio, specifically categorized under serial to parallel converters. This family provides interface solutions for expanding digital I/O capabilities in embedded systems. The G variant denotes the SDIP22 package option, distinguishing it from SOP22 and DMP24 physical form factors within the same functional family.

Serializers, Deserializers Replacement Considerations

Direct substitutes include other 16-bit serial-to-parallel converters from Nisshinbo such as the NJU3716AVC2-TE1, though pinouts and packages differ. Cross-vendor replacements require verification of logic levels, output drive strength, and package compatibility.
