Product details
Overview
SN7417NS from Texas Instruments is a hex buffer/driver IC with open-collector high-voltage outputs, designed for TTL-to-MOS level translation and driving high-current loads such as lamps or relays. It features 15 V maximum output voltage rating, 40 mA sink current capability per channel, 14 ns typical propagation delay, and operates over 0°C to 70°C. It is commonly used in indicator lamp control and bus interface circuits.
For engineers reviewing the SN7417NS datasheet, SN7417NS pinout, SN7417NS application, or SN7417NS equivalent, this page delivers verified electrical specifications, package mapping (PDIP-14), functional behavior (Y = A, open-collector), thermal metrics (RθJA = 52.1°C/W), and real-world substitution guidance - all confirmed against TI's SDLS032H production data sheet.
Technical Context
The SN7417NS implements six independent non-inverting buffers, each with an open-collector output stage rated for up to 15 V off-state voltage and 40 mA continuous sink current. Its inputs are TTL-compatible (VIH = 2 V, VIL = 0.8 V) and diode-clamped to suppress transmission-line effects.
It operates at VCC = 4.75–5.25 V, exhibits 0.4 V typical VOL at 16 mA load, and delivers 6–10 ns tPLH/tPHL switching times under 110 Ω/15 pF conditions. The device does not source current; all outputs require external pull-up networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VO(max) | 15 V - Safe off-state output voltage limit; enables direct interface with 12 V logic or lamp circuits without level-shifting. |
| IOL(max) | 40 mA - Maximum sink current per output; supports driving LEDs, relays, or multiple TTL inputs simultaneously. |
| tPD | 14 ns typical - Propagation delay determines maximum usable frequency in digital timing paths (e.g., ≤35 MHz clocked operation). |
| VCC Range | 4.75–5.25 V - Tight supply tolerance ensures stable operation in regulated 5 V systems; excludes 3.3 V compatibility. |
| VOL @ 16 mA | 0.4 V max - Low saturation voltage preserves noise margin when driving standard TTL inputs or low-threshold loads. |
| Operating Temp | 0°C to 70°C - Commercial-grade temperature range; suitable for consumer electronics and industrial control panels. |
| RθJA | 52.1°C/W - Thermal resistance of PDIP package; informs heatsinking requirements for sustained 40 mA per channel operation. |
Pinout & Package
SN7417NS is supplied in a 14-pin plastic dual in-line package (PDIP-N), body size 19.30 mm × 6.35 mm, with through-hole mounting and RoHS-compliant NiPdAu lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A, 5A, 6A | Input | Independent TTL-compatible digital inputs; each controls one open-collector output buffer. |
| 1Y, 2Y, 3Y, 4Y, 5Y, 6Y | Output | Open-collector outputs requiring external pull-up; capable of sinking up to 40 mA at ≤15 V. |
| GND (Pin 7) | Ground Reference | Common return path for all internal circuitry and output current sinks. |
| VCC (Pin 14) | Power Supply | 5 V nominal supply input; powers internal logic but does not drive outputs directly (outputs are open-collector). |
| NC (Pins 1, 5, 11, 13) | No Connection | Unbonded pins; must remain unconnected on PCB to avoid parasitic coupling or mechanical stress. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-to-MOS level translation | Enables direct interfacing between 5 V TTL logic and higher-voltage MOS or discrete loads (e.g., 12 V LED strings) without external level shifters. |
| High sink-current capability | 40 mA per output allows driving multiple TTL inputs (fan-out ≥20) or medium-power indicators without buffering. |
| Open-collector architecture | Supports wired-AND logic, shared-bus configurations, and flexible pull-up selection (voltage, speed, power trade-offs). |
| Input diode clamping | Reduces ringing and overshoot on long traces, simplifying layout in noisy or high-speed digital subsystems. |
| Commercial temperature grade | Validated for 0°C to 70°C operation - optimized for cost-sensitive consumer, computing, and peripheral applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex open-collector buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN7407N | 30 V output rating (vs. 15 V), otherwise identical pinout, timing, and drive strength. | Suitable where higher off-state voltage tolerance is required (e.g., 24 V lamp or relay systems). | Select SN7407N if interfacing with >15 V loads; SN7417NS is preferred for cost-sensitive 12 V-only designs due to tighter process control. |
| 74LS07N | Lower IOL (24 mA max), same 30 V rating, slightly slower (15 ns typ), LS-family power consumption (~19 mW). | Better suited for low-power, noise-immune environments where full 40 mA is unnecessary. | Choose 74LS07N when system-level power budget is constrained and 24 mA sink suffices; SN7417NS offers superior drive for demanding loads. |
Compared with SN7407N and 74LS07N, the SN7417NS provides optimal balance of 15 V robustness, 40 mA drive, and commercial-temperature reliability - making it ideal for cost-driven 12 V indicator and relay interfaces where excess voltage margin is unnecessary.

FAQ
What is the maximum output voltage rating for SN7417NS?
The SN7417NS has a maximum output voltage rating of 15 V when the output is in the OFF (high-impedance) state. This rating is specified in the Absolute Maximum Ratings table of TI's SDLS032H datasheet and defines the highest voltage that can be safely applied to any output pin without risk of breakdown. Exceeding 15 V may cause permanent damage to the SN7417NS.
Can SN7417NS drive a 12 V LED directly?
Yes, the SN7417NS can drive a 12 V LED directly when configured with an appropriate external pull-up resistor to +12 V. Each output is open-collector and rated for up to 15 V off-state voltage and 40 mA sink current, making it suitable for sinking LED current in common-anode configurations. Ensure the series resistor limits current to ≤40 mA and accounts for the SN7417NS's 0.4 V typical VOL at rated load.
What is the operating supply voltage range for SN7417NS?
The SN7417NS operates over a VCC supply range of 4.75 V to 5.25 V, as defined in the Recommended Operating Conditions section of the TI datasheet. This tight 5% tolerance reflects its design for stable, regulated 5 V systems. Operation outside this range - including at 3.3 V or 12 V - is not supported and may result in incorrect logic behavior or device damage.
Does SN7417NS require pull-up resistors on its outputs?
Yes, SN7417NS outputs are open-collector and inherently cannot source current. External pull-up resistors are mandatory to establish a valid HIGH logic level. The value depends on load requirements: lower resistance (e.g., 1–4.7 kΩ to +5 V or +12 V) yields faster rise times and higher drive strength, while higher resistance reduces power consumption but increases susceptibility to noise and slows switching.
How many inputs and outputs does SN7417NS have?
The SN7417NS contains six independent non-inverting buffer channels: Pins 1, 3, 5, 9, 11, and 13 serve as inputs (1A–6A), and Pins 2, 4, 6, 8, 10, and 12 serve as corresponding open-collector outputs (1Y–6Y). Two additional pins - Pin 7 (GND) and Pin 14 (VCC) - provide power connections, while Pins 1, 5, 11, and 13 are marked NC (no internal connection) in the PDIP-14 package.
