Product details
Overview
SN7416NS from Texas Instruments is a TTL hex inverter buffer/driver with six independent open-collector high-voltage outputs, designed for level-shifting from TTL to MOS logic and driving high-current loads such as indicator lamps and relays. It operates at 0°C to 70°C, supports 5 V supply, delivers up to 40 mA sink current per output, and features 15 V maximum output breakdown voltage.
For engineers reviewing the SN7416NS datasheet, SN7416NS pinout, SN7416NS application, or SN7416NS equivalent, this device is selected for high-voltage interface tasks requiring TTL-compatible inputs, robust sink capability, and compatibility with legacy industrial control and display systems.
Technical Context
The SN7416NS implements six identical inverting buffer stages, each with an open-collector NPN output transistor enabling wired-OR logic and direct connection to external pull-up networks. Its input stage includes clamping diodes for transient protection and compatibility with standard TTL logic families.
It uses bipolar TTL technology with resistor-transistor logic (RTL) input and Darlington-like output configuration, supporting high-voltage off-state tolerance (15 V) and fast propagation delays (tPLH = 10 ns, tPHL = 15 ns at VCC = 5 V, CL = 15 pF). No internal pull-ups or logic-level translation circuitry is integrated.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Hex inverter buffer with true (non-inverted) output logic polarity relative to input - Y = A̅ |
| Output Type | Open-collector - requires external pull-up for high-level assertion; enables wired-AND/wired-OR bus interfacing |
| Max Output Voltage (VOH) | 15 V - supports direct interface to 12 V lamps, relays, and older MOS circuits without level-shifter ICs |
| Sink Current (IOL) | 40 mA per output - sufficient to drive LEDs, small solenoids, and electromechanical relays directly |
| Supply Voltage (VCC) | 4.75–5.25 V - tightly regulated 5 V operation; not rated for 3.3 V or wide-range supplies |
| Propagation Delay | tPLH = 10 ns, tPHL = 15 ns - suitable for medium-speed digital control, not high-frequency clock distribution |
| Input Compatibility | Fully compatible with standard TTL (VIH = 2 V, VIL = 0.8 V); no Schmitt-trigger or hysteresis |
Pinout & Package
SOP–NS package: 14-pin small-outline plastic package, 0.150" (3.81 mm) body width, 1.27 mm lead pitch, 1.75 mm max height, RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A–6A | Input terminals | Active-high TTL-compatible inputs; internally clamped to GND via diodes for ESD/overvoltage protection |
| 1Y–6Y | Open-collector outputs | NPN collector outputs; must be externally pulled up to define high state; sink current only |
| 7 | GND | Ground reference for all inputs, outputs, and internal biasing; common return path |
| 14 | VCC | +5 V power supply; powers internal TTL logic and output stage bias; decoupling required near pin |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage open-collector outputs | 15 V breakdown rating enables direct drive of 12 V indicator lamps and relay coils without external transistors |
| 40 mA sink capability per output | Eliminates need for discrete driver transistors in low-to-medium power switching applications |
| TTL-compatible inputs with clamping diodes | Reduces external protection component count in noisy industrial environments |
| Hex configuration with independent channels | Supports parallel control of six separate loads (e.g., status LEDs, relay banks, address decoders) |
| Standard SOP–NS footprint | Enables drop-in replacement for SN7406NSR and compatibility with automated SMT assembly lines |
Applications
| Industrial Control Panels | Legacy Display Drivers |
|---|---|
Use Scenario: Driving 12 V incandescent panel lamps and electromagnetic relays in factory HMIs and PLC I/O modules. IC Role / Device Role / Timing Role: Level-shifting inverter buffer providing TTL-to-12 V interface with current sinking capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN7406NSR | 30 V output breakdown rating; same 40 mA sink, identical SOP–NS package and pinout | Better suited for 24 V lamp/relay interfaces; higher voltage margin increases safety in variable-load conditions | Select SN7406NSR when interfacing to >15 V loads; otherwise SN7416NS offers tighter voltage matching for 12 V systems |
| SN7416N | Same electrical specs but in 14-pin PDIP (N) through-hole package; 0°C to 70°C range, no RoHS exemption | Used in legacy prototyping, repair, and through-hole production where SOP reflow is unavailable | Choose SN7416N for hand-soldered prototypes or field-replaceable modules; SN7416NS enables automated SMT manufacturing |
Compared with SN7406NSR, SN7416NS trades 15 V output headroom for tighter voltage alignment with common 12 V systems; compared with SN7416N, it provides modern SMT manufacturability while retaining identical logic behavior and timing.

FAQ
What is the maximum output voltage rating for SN7416NS?
The SN7416NS has a minimum output breakdown voltage of 15 V, meaning it can safely sustain up to 15 V at its open-collector outputs when in the off (high-impedance) state. This rating is confirmed in the absolute maximum ratings table and applies under recommended operating conditions with proper heat dissipation.
Can SN7416NS operate from a 3.3 V supply?
No, SN7416NS is specified only for 4.75–5.25 V operation. Its TTL input thresholds (VIH = 2 V, VIL = 0.8 V) and internal biasing require nominal 5 V; operation below 4.75 V may cause marginal noise immunity and undefined output states. It is not 3.3 V tolerant or compatible.
Does SN7416NS include internal pull-up resistors on its outputs?
No, SN7416NS has purely open-collector outputs with no internal pull-ups. Each output (1Y–6Y) must be externally pulled up to a positive voltage rail (e.g., 5 V, 12 V, or 15 V) via a discrete resistor to establish a valid high logic level when the output is inactive.
What is the thermal resistance (θJA) of the SN7416NS SOP–NS package?
The SN7416NS in the SOP–NS package has a junction-to-ambient thermal resistance (θJA) of 76°C/W, as specified in the absolute maximum ratings table. This value assumes standard JEDEC test board conditions and must be factored into power dissipation calculations for continuous 40 mA sink operation across multiple channels.
Is SN7416NS pin-compatible with SN7406NSR?
Yes, SN7416NS and SN7406NSR share identical SOP–NS package dimensions, 14-pin layout, and pin functions - including 1A–6A inputs, 1Y–6Y outputs, GND (pin 7), and VCC (pin 14). They differ only in output breakdown voltage (15 V vs. 30 V) and are electrically interchangeable where voltage requirements align.
