SN75113N - Dual Differential Line Driver | Texas Instruments
MPN: SN75113N ✓ نشطSN75113N نظرة عامة
A differential line driver is an interface IC that converts complementary logic signals into a balanced pair of outputs. Differential signaling helps reject common-mode noise, reduces sensitivity to ground offsets, and supports dependable communication over cables or PCB traces where a single-ended driver may be vulnerable to interference. The SN75113 combines two such channels with separate output-pair controls and a common control, providing flexible bus-management options in digital systems.
The SN75113 family provides the features associated with the SN75114 line drivers while adding dedicated driver output controls. According to the manufacturer product description, individual controls are available for each output pair, together with a common control for both pairs. When a relevant output control is low, its associated output enters a high-impedance state. This tri-state behavior permits multiple driver sources to be connected to a shared bus when only one source is active at a time.
The SN75113N is identified as a 2/0 driver, meaning two driver outputs and no receiver inputs. Its differential output structure is intended for balanced digital interfaces, including point-to-point links, backplanes, test equipment, industrial data acquisition, and older computer peripheral buses. The 16-pin PDIP format also supports through-hole assembly and prototyping workflows, although it occupies more board area than a comparable surface-mount package.
Designers should account for the 4.75 V to 5.25 V supply requirement and confirm that the connected logic family uses compatible voltage levels. Output-enable and common-enable logic must be sequenced so that no two enabled drivers contend on the same bus. Signal-integrity work should include controlled-impedance routing, appropriate termination at the receiver, and return-path continuity for the differential pair.
SN75113N is suitable when a legacy or industrial system specifically requires a dual differential line driver in a 16-pin PDIP package. For new compact designs, a surface-mount equivalent may reduce board area, but it is not automatically a drop-in replacement because package dimensions, lead geometry, pin functions, and electrical limits must all be reviewed before substitution.
This page combines manufacturer product information, distributor identification, package details, replacement guidance, application analysis, and comparison data to support component selection and board-level implementation. It also distinguishes true same-footprint alternatives from related SN75113-family devices that do not provide identical output-control behavior.

التطبيقات النموذجية
SN75113N مناسب لـ 6 التطبيقs: Balanced Digital Backplane, Point-to-Point Differential Data Link, Multi-Source Communication Bus, Industrial Test and Measurement Equipment, Legacy Computer Peripheral Interface, Data Acquisition Front End.
Balanced Digital Backplane
The SN75113N can drive two balanced channels on a backplane where the system requires selectable source participation. Its two differential driver channels operate from a 4.75 V to 5.25 V supply, and each output pair can be disabled independently or through the common control. Keeping the disabled output in a high-impedance state allows several sources to share a bus when the enable logic guarantees that only one source drives at a time. The design should use balanced routing, continuous return paths, and receiver-side or source-side termination selected for the actual board impedance.
Point-to-Point Differential Data Link
Use the SN75113N when a legacy system needs two point-to-point differential outputs driven from 5 V-compatible logic. The device provides two driver channels, no receiver inputs, and three-state capability, allowing either output pair to be disconnected when the link is not active. In this topology, the two differential channels may represent related data, control, and status paths. Maintain matched routing between each positive and negative trace, verify the receiver's input thresholds against the SN75113 output characteristics, and avoid using the driver output as a general-purpose logic output without accounting for its line-driving behavior.
Multi-Source Communication Bus
The SN75113N fits a multi-source bus architecture that relies on tri-state output control rather than passive isolation. Two individual output-pair controls and a common control provide the logic needed to select sources, while the associated inactive output enters a high-impedance state. With a 4.75 V to 5.25 V supply requirement, the circuit suits established 5 V digital systems. The control design must guarantee break-before-make behavior so that one channel is disabled before another is enabled, preventing output contention and excessive current through the driver stages.
Industrial Test and Measurement Equipment
The SN75113N can provide differential drive capability in 5 V industrial instrumentation that must interface with balanced inputs over cable or board-level interconnects. Two independent driver pairs offer flexibility for driving a measurement channel and a related control or synchronization signal. Differential signaling improves common-mode rejection compared with a single-ended output, while the high-impedance mode can isolate a source during calibration or bus sharing. Cable length, connector loss, grounding, shielding, and receiver termination must be characterized together because driver timing and output-current limits determine the usable reach.
Legacy Computer Peripheral Interface
The SN75113N is appropriate for maintaining or repairing legacy 5 V computer peripheral interfaces that depend on a dual differential driver with controlled tri-state outputs. Its 16-pin PDIP package makes it convenient for through-hole repair boards and prototypes, while its 2/0 organization matches systems that need transmission paths only. The driver should be paired with the original receiver or transceiver when the interface includes bidirectional signaling. Confirm the exact pinout, enable polarity, and output levels against the system schematic before substituting it for a device with a different function or package.
Data Acquisition Front End
The SN75113N can act as the line-driver stage between control logic and a balanced data-acquisition or synchronization interface. Two differential outputs provide a practical way to transport complementary signals with reduced common-mode sensitivity, and each output pair can be disabled when the acquisition path is not active. Because the SN75113N is a driver rather than a complete receiver, the acquisition chain still requires compatible input circuitry, suitable bandwidth, conversion hardware, and protection. Validate timing margin, termination, and supply noise at the selected operating clock before using the outputs as precision excitation signals.

ملاحظات التصميم
Do not assume that a related SN75114-family device is interchangeable merely because both are differential line drivers. The SN75113 adds individual output-pair controls and a common control, while the SN75114 lacks that documented control arrangement. Verify every pin, enable polarity, output-disable behavior, and supply requirement before replacing an SN75113N in an existing schematic or PCB.
Route each differential output as a pair with matched geometry and a continuous reference plane. Keep stubs short and provide an uninterrupted return path beneath the pair. Route the individual and common output controls away from differential output nodes, especially in systems with fast transitions, because coupling from enable circuitry into a balanced signal can degrade receiver performance even when the common-mode voltage remains unchanged.
Design the SN75113N around its 4.75 V to 5.25 V operating supply range and use local supply bypassing close to the device. Confirm the board's power distribution does not allow transients to move the rail outside that interval. When multiple driver channels share a bus, combine break-before-make enable sequencing with adequate decoupling so that the switching of one output does not disturb the active source or unrelated logic on the board.
