SN75117D - 5V Differential Line Transceiver | Texas Instruments
MPN: SN75117D ✓ সক্রিয়SN75117D সারাংশ
A differential line transceiver is an interface IC that transmits and receives data across a balanced connection. The transmitter converts a single-ended logic signal into a differential pair, while the receiver detects the voltage difference between the two conductors. Differential signaling rejects common-mode noise, reduces electromagnetic interference, and supports dependable communication over cables or board-level twisted-pair interconnects.
The SN75117D features TTL-compatible driver inputs and a TTL-compatible receiver output. Its driver output can be placed in a three-state condition, allowing the driver to be disabled when shared bus direction control is required. The receiver supports differential line operation and includes receiver-output strobe control as a family-level feature of the SN75117 device.
The device is intended for balanced data links where low propagation delay, noise immunity, and bus direction control are important. Its 30 ns maximum transmit delay is suitable for moderate-speed control and instrumentation links, while the 75 ns maximum receive delay provides a defined upper limit for receiver-side timing. The single 5 V supply also simplifies interfacing with TTL and other 5 V digital systems.
Typical uses include industrial equipment links, instrumentation buses, data acquisition systems, telecommunications equipment, and computer peripherals. In these systems, the SN75117D can place a balanced signal onto a cable, recover the signal at the far end, and provide a logic-compatible receiver output to downstream digital circuitry.
PCB design should preserve the differential signal path, use a controlled ground reference, and place termination and protection components close to the line interface. The receiver and driver timing should be checked against the connected cable length and system clock requirements. Power decoupling should follow the manufacturer datasheet layout to minimize supply disturbance during output transitions.
This product page combines the manufacturer's device features with practical interface-circuit guidance, timing considerations, package information, sourcing instructions, and design guidance for engineers evaluating the SN75117D in a differential communications design.

সাধারণ ব্যবহার
SN75117D এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: Industrial Equipment Data Links, Instrumentation and Test Systems, Data Acquisition Equipment, Telecommunications Equipment, Computer Peripherals and Legacy Interfaces, Balanced Sensor and Controller Links.
Industrial Equipment Data Links
The SN75117D is suitable for short, balanced interconnections between industrial control equipment, remote modules, and data-acquisition units. Its differential driver rejects common-mode disturbance, while the 5 V single supply and TTL-compatible receiver output simplify connection to 5 V logic. The 30 ns maximum transmit delay and 75 ns maximum receive delay provide defined timing for moderate-speed control traffic. Engineers should use matched routing or twisted-pair cable, provide the correct line termination, and confirm that the complete cable and protection network remains within the receiver's permitted common-mode range.
Instrumentation and Test Systems
The SN75117D can connect laboratory and process-instrumentation sections through a balanced line when noise immunity and deterministic propagation timing are important. The differential receiver converts the line voltage difference into a TTL-compatible output, reducing susceptibility to shared-ground noise found in larger test systems. Its 5 V operating supply aligns with many legacy acquisition systems. Keep the analog-sensitive circuitry separated from the digital interface, terminate the line at the appropriate endpoint, and validate the 30 ns transmitter and 75 ns receiver limits against the measurement timing budget.
Data Acquisition Equipment
The SN75117D fits data-acquisition equipment that must move control or status information between a central controller and a remote signal-conditioning enclosure. Differential signaling reduces sensitivity to ground-potential differences and electrically induced noise encountered through longer cables. The three-state driver output permits the interface to relinquish the line when direction control requires it, while the receiver output strobe provides a defined control function. Use termination and surge-protection components at the connector, maintain a stable ground reference, and account for the 75 ns maximum receive delay in sampling or handshake timing.
Telecommunications Equipment
The SN75117D can support auxiliary balanced signaling paths within telecommunications equipment, including supervisory, status, or service interfaces. Its 5 V supply and TTL-compatible logic levels permit direct interfacing with conventional digital circuits, while differential line operation improves noise immunity in multi-board or cabled systems. The compact 8-pin SOIC package supports routing density without requiring a larger transceiver footprint. Keep driver and receiver return paths close to their corresponding differential conductors, avoid long unprotected stubs at the connector, and verify cable length against the application's timing requirements.
Computer Peripherals and Legacy Interfaces
The SN75117D is appropriate for legacy computer-peripheral and industrial-interface links that use balanced signaling and TTL-compatible logic. The receiver translates differential line voltage into a single-ended digital output, while the transmitter provides complementary differential drive with a three-state control path. This combination can bridge equipment whose host interface is single-ended but whose external cable benefits from differential noise rejection. Because legacy implementations may require specific terminators, protection devices, or logic inversion, confirm the complete interface function and pin behavior before integrating the device.
Balanced Sensor and Controller Links
The SN75117D can carry digital control or status signals between a controller and a remote sensor assembly where a single-ended connection would be exposed to noise. Differential operation reduces sensitivity to common-mode voltage and helps maintain signal integrity across board-to-board or cable-based paths. The 30 ns maximum transmit delay and 75 ns maximum receive delay establish clear bounds for digital control timing. Designers should use a ground reference appropriate for the equipment architecture, place line protection near the connector, and confirm that the cable and termination arrangement preserve the required signal amplitude.

ডিজাইন নোট
Route the differential pair as a controlled impedance, tightly coupled pair rather than as unrelated single-ended traces. Keep the driver and receiver connections short, avoid stubs, return the differential pair over a continuous ground reference, and place any line termination close to the receiver. This layout discipline minimizes radiated emissions and improves rejection of common-mode noise on the balanced connection.
Budget the interface timing using the maximum 30 ns transmit delay and 75 ns receive delay rather than nominal values. The transmit and receive paths contribute differently to end-to-end latency, so control software, handshaking, or data-strobe timing should allow for the slower 75 ns receiver path. Cable length, connector transitions, and termination tolerance should also be included in end-to-end timing verification.
Do not assume that every related SN751-family transceiver is pin-compatible. The family includes devices with different receiver-output strobe or enable arrangements, so a related device can differ functionally even when the package is similar. Before redesigning or substituting a part, compare the complete manufacturer pin table, three-state behavior, receiver control, supply limits, and propagation timing.
Use a stable 5 V rail for the SN75117D and keep the supply return path continuous under the package. Place the required bypass capacitor close to the supply and ground pins according to the manufacturer layout, and avoid routing noisy return current beneath the differential interface. Adequate local decoupling helps prevent driver transitions from disturbing adjacent digital circuitry.
Protect externally accessible differential lines with appropriately rated surge and ESD protection. Protection devices should be placed close to the connector and selected without disrupting the intended line impedance. Confirm the receiver's permitted common-mode range against the source, ground-potential differences, and fault conditions before finalizing the protection network.
