Product details
Overview
SN7417NSR 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 breakdown voltage, 40 mA sink current capability per channel, 14 ns typical propagation delay, and operates over 0°C to 70°C. It is used in indicator lamp drivers and bus interface circuits requiring voltage-level shifting.
For engineers reviewing the SN7417NSR datasheet, SN7417NSR pinout, SN7417NSR application, or SN7417NSR equivalent, this page delivers verified electrical specs, package mapping to SOP-14, functional role in open-collector interfacing, thermal metrics (RθJA = 85.9°C/W), and confirmed alternatives for high-voltage buffer replacement.
Technical Context
The SN7417NSR implements six independent non-inverting buffers with open-collector outputs, performing Y = A in positive logic. Each output supports up to 15 V off-state voltage and sinks up to 40 mA at VOL ≤ 0.7 V under full load.
Inputs are TTL-compatible (VIH ≥ 2 V, VIL ≤ 0.8 V) and diode-clamped to suppress transmission-line effects. The device draws 21–41 mA supply current depending on output state and operates from a 4.75–5.25 V VCC supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VO(BR) (min) | 15 V - Maximum safe off-state output voltage; enables direct interface with 12 V logic or lamp supplies without external clamping. |
| IOL (max) | 40 mA - Sustained sink current per channel; sufficient to drive LEDs, small relays, or multiple TTL inputs simultaneously. |
| tPLH/tPHL | 6–30 ns - Propagation delay range (RL = 110 Ω / 150 Ω, CL = 15/50 pF); supports reliable operation up to ~35 MHz clocked applications. |
| VCC Range | 4.75–5.25 V - Tight supply tolerance ensures stable operation in regulated 5 V systems; excludes wider industrial rails. |
| Operating Temp | 0°C to 70°C - Commercial-grade temperature range; suitable for consumer electronics and non-extended industrial environments. |
| PD (typ) | 145 mW - Total quiescent + dynamic power dissipation at 25°C; enables use in thermally constrained PCB layouts without forced cooling. |
Pinout & Package
SOP-14 (NS) package: 8.65 mm × 3.91 mm body, gull-wing leads, RoHS-compliant NiPdAu finish, MSL Level-1 (260°C reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A, 5A, 6A | Input | TTL-compatible digital inputs; must be tied to VCC or GND if unused to prevent floating states. |
| 1Y, 2Y, 3Y, 4Y, 5Y, 6Y | Open-collector output | Active-low sinking outputs; require external pull-up to define high state; tolerate up to 15 V when off. |
| VCC | Power supply | 5 V nominal supply input; bypass capacitor (0.1 µF) required adjacent to pin for noise suppression. |
| GND | Ground reference | Common return path for all inputs, outputs, and internal circuitry; low-impedance connection essential. |
| NC (pins 7, 11, 15) | No internal connection | Unbonded pins; no electrical function; may be left unconnected or grounded for mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage open-collector outputs | 15 V breakdown rating enables direct connection to 12 V peripherals (e.g., LED arrays, relay coils) without level-shifter ICs. |
| 40 mA sink per channel | Eliminates need for discrete transistor buffers in medium-current drive applications like status indicators or bus terminators. |
| TTL input compatibility | Accepts standard 0.8 V / 2.0 V logic thresholds and includes input diode clamping to reduce signal integrity issues on long traces. |
| Low propagation delay | 14 ns typical delay supports timing-critical functions such as address/data strobing in legacy parallel interfaces. |
| Diode-clamped inputs | Minimizes ringing and overshoot on unterminated lines, simplifying layout in cost-sensitive consumer designs. |
Applications
| LED Indicator Driver | Parallel Bus Interface |
|---|---|
|
Use Scenario: Driving 12 V LED status indicators in consumer audio docks and portable media players. IC Role / Device Role / Timing Role: Open-collector buffer translating 5 V TTL logic to 12 V LED anode switching; provides current sinking path.

Use Scenario: Interfacing 5 V TTL microcontrollers with 12 V MOS memory or peripheral ICs in HDTV mainboards. IC Role / Device Role / Timing Role: Voltage-level translator converting 5 V logic swings to 12 V-compatible signals via pull-up resistors. Use Value: Achieves bidirectional level shift using single-supply design; avoids dual-rail translators and associated complexity. |
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 |
|---|---|---|---|
| SN7407NSR | 30 V output breakdown (vs. 15 V); identical pinout, package, and 40 mA sink rating. | Supports higher-voltage loads (e.g., 24 V lamps); not suitable where 15 V max is required for safety or regulation compliance. | Select SN7407NSR only when >15 V output swing is needed; otherwise SN7417NSR offers tighter voltage margin and lower leakage. |
| 74LS07DR | Lower 15 mA sink current; 30 V breakdown; TTL-input compatible but higher VIL (0.8 V same, but less noise margin). | Not suitable for 40 mA loads; acceptable for low-current LEDs or logic-level translation where drive strength is secondary. | Choose 74LS07DR for cost-sensitive, low-power indicator applications; avoid where full 40 mA sink is required per channel. |
Compared with SN7407NSR and 74LS07DR, the SN7417NSR uniquely balances 15 V safety margin, 40 mA drive, and commercial-temperature reliability-making it optimal for regulated 12 V indicator and relay control where overvoltage risk must be minimized.

FAQ
What is the maximum output voltage rating for SN7417NSR?
The SN7417NSR has a minimum output breakdown voltage of 15 V, meaning it can safely withstand up to 15 V at its open-collector outputs when in the OFF (high-impedance) state. This rating is specified under absolute maximum conditions and is validated per TI's production test flow for the SN7417NSR family.
Can SN7417NSR drive a 12 V LED directly?
Yes, the SN7417NSR can directly drive a 12 V LED when used with an appropriate current-limiting resistor and external 12 V pull-up. Its 15 V output breakdown rating and 40 mA sink capability per channel make it suitable for this use case, as confirmed in TI's application guidance for SN7417NSR in indicator lamp circuits.
Is SN7417NSR pin-compatible with SN7407NSR?
Yes, SN7417NSR is pin-compatible with SN7407NSR - both use the SOP-14 (NS) package and share identical pin configuration, function mapping, and footprint. The key difference lies in output voltage rating (15 V vs. 30 V), not pinout or package dimensions.
What is the recommended bypass capacitor for SN7417NSR?
Texas Instruments recommends a 0.1 µF ceramic bypass capacitor placed as close as possible to the VCC pin of the SN7417NSR. This value is specified in TI's Power Supply Recommendations section for the SN7417NSR datasheet to suppress high-frequency noise and ensure stable operation.
Does SN7417NSR require external pull-up resistors on its outputs?
Yes, SN7417NSR requires external pull-up resistors on all open-collector outputs (1Y–6Y) to establish a defined HIGH logic level. The datasheet specifies that outputs remain high-impedance unless actively sinking current, and no internal pull-ups are integrated into the SN7417NSR die.
