Product details
Overview
SN7407DE4 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 at 5 V supply across 0°C to 70°C.
For engineers reviewing the SN7407DE4 datasheet, SN7407DE4 pinout, SN7407DE4 application, or SN7407DE4 equivalent, key selection criteria include open-collector output voltage tolerance (30 V), sink current capability (40 mA), TTL-compatible inputs, SOIC-14 package footprint, and compatibility with legacy logic interface designs requiring high-voltage drive without level-shifting circuitry.
Technical Context
The SN7407DE4 implements six independent non-inverting buffers, each with an open-collector output stage enabling wired-OR configurations and direct interfacing to loads up to 30 V. Its input structure includes diode clamping for transmission-line effect suppression and full compatibility with standard TTL families.
Each channel performs Y = A (positive logic), with no internal pull-up; external pull-up resistors are required for logic-high assertion. The device exhibits typical power dissipation of 145 mW and supports switching frequencies up to ~100 MHz under light capacitive loads, validated by tPLH/tPHL ≤30 ns at 5 V with 15 pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Type | Open-collector - enables wired-OR logic, high-voltage off-state isolation, and flexible pull-up selection |
| Max Output Voltage | 30 V - supports direct driving of lamps, relays, and MOS gates without external level shifters |
| Sink Current per Channel | 40 mA - sufficient for LED arrays, small solenoids, and multiple TTL inputs simultaneously |
| Propagation Delay | 14 ns typical - ensures timing integrity in medium-speed digital control and bus interface applications |
| Supply Voltage Range | 4.75 V to 5.25 V - tight regulation requirement for stable TTL-level operation and noise margin preservation |
| Operating Temperature | 0°C to 70°C - commercial-grade rating suitable for consumer electronics and non-military industrial equipment |
| Input Compatibility | Fully compatible with standard TTL - eliminates need for input conditioning or voltage translation circuitry |
Pinout & Package
SN7407DE4 is housed in a 14-pin SOIC (D) package measuring 8.65 mm × 3.91 mm, with gull-wing leads and RoHS-compliant NiPdAu plating. Thermal resistance RθJA is 86.8°C/W, supporting moderate-power dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input A1–A6 | Digital logic inputs accepting TTL-compatible voltage levels (VIL ≤ 0.8 V, VIH ≥ 2 V) |
| 2, 4, 6, 8, 10, 12 | Output Y1–Y6 | Open-collector outputs requiring external pull-up; capable of sinking 40 mA at ≤0.7 V saturation |
| 7 | GND | Ground reference for all inputs, outputs, and internal circuitry; must be low-impedance connection |
| 14 | VCC | +5 V supply pin; requires local 0.1 µF bypass capacitor to minimize switching noise coupling |
| NC (pins 1,5,7,11,15,17 on LCCC variant) | No connect | Not bonded internally in SOIC-14; electrically isolated and must remain unconnected |
Key Features
| Feature | Design Value |

Applications
| Industrial Control Panels | LED Status Indication |
|---|---|
Use Scenario: Driving panel-mounted indicator lamps and pilot lights in PLC I/O modules and HMI enclosures. IC Role / Device Role / Timing Role: Open-collector buffer translating 5 V TTL logic to 24 V lamp supply rails while providing current gain and electrical isolation. Use Value: Eliminates need for discrete transistors or optocouplers; 30 V output rating matches common industrial control voltages. | Use Scenario: Controlling multi-segment LED displays and status LEDs in consumer audio docks and portable media players. IC Role / Device Role / Timing Role: Level-translating buffer sinking current from red/green/blue LED anodes tied to +5 V or +3.3 V supplies. Use Value: 40 mA per channel supports bright LED drive without thermal derating; SOIC-14 footprint fits dense handheld PCB layouts. |
| Relay Driver Interface | TTL-to-MOS Logic Translation |
Use Scenario: Activating electromechanical relays in telecom power supply controllers and server rack management systems. IC Role / Device Role / Timing Role: High-current open-collector driver interfacing microcontroller GPIO to relay coil circuits operating at 12 V or 24 V. Use Value: 40 mA sink capability exceeds typical relay coil hold currents (10–30 mA); 30 V rating prevents breakdown during inductive kickback. | Use Scenario: Bridging 5 V TTL logic domains to 12 V or 15 V MOS memory or peripheral interfaces in legacy computing systems. IC Role / Device Role / Timing Role: Non-inverting buffer converting TTL output voltage swing (0.4 V/2.4 V) to MOS-compatible thresholds via external pull-up to higher rail. Use Value: Diode-clamped inputs prevent latch-up when interfacing to slower or floating MOS inputs; 14 ns delay preserves setup/hold timing margins. |
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 | Same logic function and electrical specs, but in PDIP-14 package (19.30 mm × 6.35 mm) with through-hole mounting | Better suited for prototyping, manual assembly, or high-reliability through-hole boards where SOIC reflow is impractical | Select SN7407N when board assembly uses wave soldering or hand-soldering, and thermal budget allows higher RθJA (52.1°C/W) |
| SN7407DR | Identical SOIC-14 package and specs; E4 suffix denotes TI's legacy green/RoHS-compliant packaging (NiPdAu), while DR denotes tape-and-reel packaging with same finish | No functional difference; DR is optimized for automated SMT placement with 2500-unit reels, whereas DE4 is tube-packaged | Choose SN7407DR for high-volume SMT production; SN7407DE4 remains valid for low-volume, repair, or evaluation use |
Compared with SN7407N and SN7407DR, the SN7407DE4 offers identical electrical performance in a RoHS-compliant SOIC-14 package with tube delivery-making it ideal for design validation, small-batch builds, and legacy system replacements where reel logistics are unnecessary.

FAQ
What is the maximum output voltage rating for SN7407DE4?
The SN7407DE4 has a minimum output breakdown voltage of 30 V, meaning it can safely sink current while its output is pulled up to 30 V. This rating is specified under absolute maximum conditions and applies to the SNx407 series (including SN7407DE4), distinguishing it from the 15 V-rated SNx417 variants. Exceeding 30 V risks permanent damage to the output transistor.
Does SN7407DE4 require external pull-up resistors on its outputs?
Yes, SN7407DE4 requires external pull-up resistors on all six open-collector outputs (Y1–Y6) to establish a logic-high state. The device itself only provides active-low sinking capability; without a pull-up, outputs float in the high-impedance state. Typical values range from 1 kΩ (for speed-critical 24 V loads) to 10 kΩ (for low-power 5 V logic interfaces).
Can SN7407DE4 drive multiple TTL inputs directly?
Yes, SN7407DE4 can drive multiple standard TTL inputs directly due to its 40 mA sink current rating per channel and TTL-compatible input thresholds. Each output can reliably sink the combined input current of up to six standard TTL gates (each drawing ~1.6 mA low-level input current), making it suitable for fanout expansion in control logic networks.
What is the operating temperature range for SN7407DE4?
The SN7407DE4 is rated for commercial operation from 0°C to 70°C ambient temperature. This range aligns with its SN74xx designation (versus SN54xx military-grade parts rated –55°C to 125°C) and is appropriate for indoor consumer, computing, and industrial equipment not exposed to extreme environmental conditions.
Is SN7407DE4 RoHS compliant and lead-free?
Yes, SN7407DE4 is RoHS compliant with NiPdAu lead finish, as confirmed in TI's official packaging addendum. The "E4" suffix explicitly denotes TI's green packaging standard, which meets EU RoHS Directive 2011/65/EU requirements and contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE substances above threshold limits.
