Product details
Overview
SN7407NE4 from Texas Instruments is a hex buffer/driver IC with open-collector high-voltage outputs, designed for TTL-to-MOS level translation and high-current sinking (40 mA per channel) in industrial control and indicator driving applications. It features 30 V output breakdown voltage, 14 ns typical propagation delay, and operates across 0°C to 70°C.
For engineers reviewing the SN7407NE4 datasheet, SN7407NE4 pinout, SN7407NE4 application, or SN7407NE4 equivalent, this page delivers verified electrical specs, PDIP-14 package details, functional truth table (Y = A), sink-current capability, and real-world use cases including relay drivers and LED arrays - all confirmed from TI's SDLS032H production data sheet.
Technical Context
This device implements six independent non-inverting buffers with open-collector outputs, enabling wired-OR logic and direct interface to higher-voltage loads. Each channel supports up to 40 mA sink current at VOL ≤ 0.7 V and withstands 30 V on the output when off.
Inputs are TTL-compatible (VIL ≤ 0.8 V, VIH ≥ 2 V), diode-clamped to suppress transmission-line effects, and fully compatible with standard 74-series logic families. The device draws 21–41 mA supply current depending on output state and load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Type | Open-collector - enables wired-OR bus configurations and external pull-up to arbitrary voltage (≤30 V) |
| Max Sink Current | 40 mA per output - sufficient to drive LEDs, relays, or MOS gate inputs without external transistors |
| Output Breakdown Voltage | 30 V - allows direct interfacing with 12 V/24 V industrial control rails and lamp loads |
| Propagation Delay | 10 ns typical (tPLH/tPHL) - supports reliable operation in systems up to ~50 MHz clock domains |
| Supply Voltage Range | 4.75 V to 5.25 V - tightly regulated 5 V TTL-compliant operation; not rated for 3.3 V or wide-VCC |
| Input Compatibility | Fully compatible with standard TTL logic families - VIH ≥ 2 V, VIL ≤ 0.8 V, no level-shifting circuitry required |
| Operating Temperature | 0°C to 70°C - commercial-grade rating suitable for consumer electronics and non-military embedded systems |
Pinout & Package
SN7407NE4 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 |
| 1Y, 2Y, 3Y, 4Y, 5Y, 6Y | Output | Open-collector outputs - must be externally pulled up; sink current only, no sourcing capability |
| GND (Pin 7) | Ground Reference | Common return path for all inputs, outputs, and internal logic; mandatory connection for stable operation |
| VCC (Pin 14) | Power Supply | 5 V nominal supply input; powers internal TTL circuitry; bypass capacitor (0.1 µF) required near pin |
| NC (Pins 1, 5, 11, 13) | No Connection | Internally unconnected pins - must remain floating; no routing or termination required |
Key Features
| Feature | Design Value |
|---|---|
| TTL-to-MOS level translation | Enables direct interface between 5 V TTL logic and 12–24 V MOS circuits without discrete level shifters |
| High sink-current capability | 40 mA per output supports driving multiple TTL inputs, LEDs, or small-signal relays directly |
| 30 V output voltage tolerance | Allows safe operation with external pull-ups to industrial voltages - eliminates need for external protection diodes |
| Input diode clamping | Reduces ringing and signal integrity issues on long traces or unterminated lines in backplane applications |
| Hex-channel independence | Six isolated buffers enable mixed-function designs - e.g., three channels for display control, three for sensor interface |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN7407N | Identical electrical specs and PDIP-14 package; differs only in RoHS compliance marking (E4 suffix denotes lead-free finish) | No functional difference - both rated for 0°C to 70°C, 40 mA sink, 30 V output | Select SN7407NE4 for RoHS-compliant production; SN7407N may be used where legacy Pb-based assembly is permitted |
| SN7417N | Same PDIP-14 package but lower 15 V output breakdown voltage and identical 40 mA sink capability | Not suitable for 24 V relay or lamp loads; limited to ≤15 V external pull-up applications | Choose SN7417N only when system voltage is capped at 15 V and cost optimization is prioritized over voltage margin |
Compared with SN7407N, SN7407NE4 offers identical performance with certified RoHS compliance; versus SN7417N, it provides critical 30 V output tolerance essential for industrial 24 V control interfaces - making SN7407NE4 the preferred choice for robust, high-voltage buffer applications.

FAQ
What is the maximum output voltage rating for SN7407NE4?
The SN7407NE4 has a guaranteed minimum output breakdown voltage of 30 V. This means each open-collector output can safely tolerate up to 30 V when in the OFF (high-impedance) state - enabling direct use with 12 V and 24 V industrial power rails without external protection components. This rating is confirmed in TI's SDLS032H datasheet Section 6.3 (Recommended Operating Conditions) and Section 6.1 (Absolute Maximum Ratings).
Can SN7407NE4 operate from a 3.3 V supply?
No, SN7407NE4 is not specified for 3.3 V operation. Its recommended VCC range is 4.75 V to 5.25 V, and absolute maximum supply voltage is only 7 V. Applying 3.3 V will result in undefined logic thresholds, excessive propagation delay, and potential failure to drive TTL-compatible loads. For 3.3 V systems, consider logic-level translators or newer 74LVC-series buffers instead of SN7407NE4.
Does SN7407NE4 support wired-OR logic connections?
Yes, SN7407NE4 supports wired-OR logic via its open-collector outputs. Multiple SN7407NE4 outputs (or other open-collector devices) can share a common pull-up resistor and node, allowing logical OR behavior without additional gates. This is explicitly enabled by the open-collector architecture and is widely used in interrupt buses and status aggregation - confirmed in the Functional Description (Section 8.1) and Logic Diagram of the SN7407NE4 datasheet.
What is the purpose of the NC pins on SN7407NE4?
SN7407NE4 has four NC (No Connect) pins: 1, 5, 11, and 13. These pins have no internal connection to the die and serve only mechanical or historical packaging purposes. They must remain unconnected - neither grounded nor tied to VCC. Routing traces or adding terminations to NC pins may cause parasitic coupling or violate TI's layout recommendations in Section 11.1 of the datasheet.
How much current can SN7407NE4 sink per output channel?
SN7407NE4 is rated for a maximum sink current of 40 mA per output channel under recommended operating conditions (VCC = 5 V, TA = 25°C). This is validated in Section 6.3 (IOL = 40 mA) and Section 6.5 (VOL ≤ 0.7 V at 40 mA). Exceeding this limit risks thermal overstress or parametric shift - always verify total power dissipation (PD ≈ VOL × IOL) and board-level thermal design when operating near 40 mA continuously.
