DS75113N

Overview

The DS75113N is a dual tri-state differential line driver manufactured by National Semiconductor. It features two independent drivers capable of driving high-impedance loads, making it suitable for bus-oriented systems. The device operates with a supply voltage range typically from 4.75 V to 5.25 V and draws a quiescent current of approximately 8 mA. It utilizes a standard 16-pin DIP package for through-hole mounting. The inputs are compatible with TTL logic levels, ensuring reliable interfacing with digital control circuits.

Feature Summary

• Provides two independent differential line drivers within a single package
• Features tri-state output capability for efficient bus sharing
• Ensures compatibility with standard TTL input logic levels

Applications

• Bus-oriented communication systems requiring differential signaling
• High-speed data transmission interfaces
• Digital logic level translation between different voltage domains

Procurement Notes

Verify the manufacturer origin as National Semiconductor or Texas Instruments, noting that National Semiconductor was acquired by TI. Confirm the package type is a 16-pin DIP and check for RoHS compliance status, as older batches may contain lead. Ensure the part number suffix 'N' corresponds to the specific plastic DIP variant required for your assembly process.

Selection Notes

Select this component when a dual differential driver with tri-state control is required for bus applications. Compare against similar parts like the SN75113 or DS75113M if surface mount options are needed. Verify that the operating temperature range meets the environmental requirements of the target system before finalizing the design.

Part Context

The DS75113 belongs to the DS75 series of line drivers produced by National Semiconductor. This family includes various differential drivers such as the DS75110 and DS75114. These components are widely used in telecommunications and industrial control systems where noise immunity and long-distance signal integrity are critical.

Replacement Considerations

The SN75113 is a direct functional equivalent often available from Texas Instruments. Other compatible alternatives include the MC3487 or SN75115 depending on specific pinout and electrical parameter requirements.
