Product details
Overview
SN75462PE4 from Texas Instruments is a dual high-voltage, high-current NAND peripheral driver IC designed for logic-level interfacing to power loads. It delivers 300 mA continuous output current per channel, supports up to 35 V off-state output voltage, operates from 4.75–5.25 V supply, and features TTL-compatible diode-clamped inputs with no latch-up at 30 V after conducting 300 mA. It is used in relay drivers, lamp drivers, and MOSFET gate drivers in industrial control panels.
For engineers reviewing the SN75462PE4 datasheet, SN75462PE4 pinout, SN75462PE4 application, or SN75462PE4 equivalent, this page provides verified functional identity, validated 8-pin PDIP package mapping, confirmed NAND logic behavior with open-collector NPN outputs, absolute maximum ratings (35 V VO, 400 mA IOUT), and two documented alternative part numbers with technical and application differences.
Technical Context
The SN75462PE4 implements two independent NAND-gated NPN transistor drivers with internal base resistors (1.6 kΩ, 4 kΩ) and emitter-follower output stages. Each channel uses positive-logic NAND gating where both inputs must be high to turn off the output transistor - resulting in an active-low, open-emitter configuration requiring external pull-up or load connection to VCC or higher voltage rail.
It is characterized for 0°C to 70°C operation and features diode-clamped TTL-compatible inputs, 0.25 V typical low-level output voltage at 100 mA, and medium-speed switching (tPHL ≤ 50 ns, tPLH ≤ 65 ns at VCC = 5 V, TA = 25°C). The device avoids latch-up under transient overvoltage conditions up to 30 V while sourcing 300 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | NAND gate driving NPN output transistor - output goes high-impedance when both inputs high; otherwise sinks current. |
| Max Output Current | 300 mA continuous per channel - sufficient to directly drive relays, lamps, or small solenoids without external amplification. |
| Off-State Output Voltage | 35 V - enables interface to loads operating above 5 V supply, e.g., 24 V industrial control circuits. |
| Supply Voltage Range | 4.75 V to 5.25 V - tightly regulated 5 V TTL/CMOS compatibility; not suitable for wide-input or battery-powered systems. |
| Input Compatibility | TTL-compatible with diode clamping - accepts standard 0.8 V / 2.0 V logic thresholds and protects against input overvoltage transients. |
| Switching Speed | tPHL ≤ 50 ns, tPLH ≤ 65 ns - supports medium-frequency digital control (≤10 MHz enable/disable toggling) but not high-speed data transmission. |
| Operating Temperature | 0°C to 70°C - commercial-grade rating; unsuitable for automotive under-hood or extended industrial environments. |
Pinout & Package
SN75462PE4 is supplied in an 8-pin plastic dual in-line package (PDIP, P package) with 0.3-inch width, through-hole mounting, and copper lead frame for improved thermal performance and reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input A of Channel 1 | First NAND input; TTL-compatible, diode-clamped, referenced to GND. |
| 1B | Input B of Channel 1 | Second NAND input; identical electrical characteristics to 1A. |
| 1Y | Output Y of Channel 1 | Open-emitter NPN collector tied to VCC externally; sinks current when either input low. |
| GND | Ground Reference | Common return path for inputs, outputs, and internal bias networks. |
| VCC | Positive Supply | 5 V nominal supply for internal logic and base drive circuitry only - not connected to output load path. |
| 2B | Input B of Channel 2 | Second NAND input of second independent driver; electrically isolated from Channel 1. |
| 2A | Input A of Channel 2 | First NAND input of second driver; matches 1A/1B timing and threshold specs. |
| 2Y | Output Y of Channel 2 | Independent open-emitter output; requires separate external load connection and pull-up or high-side supply. |
Key Features
| Feature | Design Value |
|---|---|
| No latch-up at 30 V | Guaranteed immunity to destructive latch-up when output is exposed to 30 V while sinking 300 mA - critical for relay coil flyback protection. |
| Diode-clamped TTL inputs | Integrated input protection diodes limit VI to −1.5 V to 5.5 V, enabling robust interfacing with legacy 5 V logic families without external clamps. |
| Copper lead frame PDIP | Enhanced thermal conductivity vs. standard PDIP - lowers junction-to-ambient θJA, supporting sustained 300 mA operation at elevated ambient temperatures. |
| High-voltage output capability | 35 V off-state rating allows direct connection to 24 V PLC I/O modules, pneumatic valve drivers, or AC solid-state relay control circuits. |
| Dual independent channels | Two functionally isolated NAND drivers on one die - reduces board space and component count versus discrete transistor + gate solutions. |
Applications
| Industrial Relay Control | DC Lamp & LED Array Driver |
|---|---|
|

Use Value: Delivers 300 mA per channel - sufficient for 5 W lamps or 20× 150 mA LEDs - with <65 ns propagation delay for responsive visual feedback. |
| MOSFET Gate Driver | Memory & Peripheral Buffer |
|
Use Scenario: Level-shifting and current boosting for logic-level N-channel MOSFET gates in 5–24 V power-switching applications. IC Role / Device Role / Timing Role: Acts as inverting buffer with high-current sink capability to rapidly discharge MOSFET gate capacitance during turn-off. Use Value: 300 mA peak sink current ensures sub-microsecond gate discharge; 35 V VO rating accommodates gate drive rails up to 24 V. |
Use Scenario: Isolating and strengthening address/data lines between microcontrollers and parallel EEPROM or SRAM devices. IC Role / Device Role / Timing Role: Dual NAND configured as non-inverting buffers (via external pull-ups) to drive capacitive memory bus loads beyond MCU drive limits. Use Value: 0.25 V VOL at 100 mA maintains valid logic LOW under heavy bus loading; diode-clamped inputs prevent noise-induced glitches on shared buses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-current NAND driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN75462P | Identical electrical specs and PDIP-8 package; differs only in RoHS compliance marking (SN75462PE4 is RoHS-compliant with NiPdAu lead finish, SN75462P may be legacy non-RoHS variant). | No functional difference; both rated for 0°C to 70°C and share identical pinout, timing, and drive capability. | Select SN75462PE4 for new designs requiring RoHS compliance and traceable sourcing; SN75462P may be available in legacy inventory only. |
| ULN2003A | Seven-channel Darlington array with integrated clamp diodes; 500 mA per channel but slower (tPLH ≈ 250 ns), open-collector (not open-emitter), and no NAND logic - requires external gates. | Better suited for high-count, low-speed loads (e.g., stepper motor phases); lacks built-in logic, so external NAND required for same functionality. | Choose ULN2003A when driving >2 loads or needing integrated flyback diodes; choose SN75462PE4 when NAND logic integration and faster switching are required. |
Compared with SN75462P, SN75462PE4 offers identical performance with certified RoHS compliance; compared with ULN2003A, it trades channel count and flyback protection for integrated NAND logic and 4× faster switching - making it optimal for compact, dual-load, logic-gated industrial interfaces.

FAQ
What is the logic function and output structure of the SN75462PE4?
The SN75462PE4 implements two independent dual-input NAND gates, each driving an NPN transistor with open-emitter output. When both inputs are high, the output transistor turns off (high-impedance state); otherwise, it sinks current from an external load connected between VCC (or higher voltage rail) and the output pin. This architecture requires external pull-up or load connection to function as an active-low driver.
Can the SN75462PE4 drive a 24 V relay coil directly?
Yes, the SN75462PE4 can directly drive a 24 V relay coil because its off-state output voltage rating is 35 V and it supports continuous 300 mA per channel. The output stage is an open-emitter NPN transistor - connect the relay coil between +24 V and the 1Y or 2Y pin, with the coil's other terminal grounded. Ensure flyback energy is dissipated safely, as the device itself does not include internal clamp diodes.
What is the maximum operating temperature range for the SN75462PE4?
The SN75462PE4 is characterized for operation from 0°C to 70°C ambient temperature - a commercial-grade specification. It is not rated for extended temperature ranges such as −40°C to 125°C. For designs requiring wider thermal tolerance, consider the military-grade SN55462 variant, which operates from −55°C to 125°C in CDIP or LCCC packages.
Does the SN75462PE4 have built-in flyback diodes for inductive loads?
No, the SN75462PE4 does not include internal flyback (clamping) diodes. Its output stage consists of open-emitter NPN transistors without integrated protection. When driving inductive loads like relays or solenoids, an external flyback diode must be connected across the load - cathode to the positive supply rail, anode to the output pin - to suppress voltage spikes during turn-off.
How does the SN75462PE4 differ from the ULN2003A in practical use?
The SN75462PE4 integrates NAND logic and delivers faster switching (≤65 ns vs. ~250 ns), but offers only two channels and no built-in flyback diodes. The ULN2003A provides seven Darlington drivers with integrated clamp diodes and 500 mA rating, but requires external logic gates for NAND functionality and is significantly slower. Choose SN75462PE4 for compact, logic-integrated dual-load control; ULN2003A for multi-channel, diode-protected, lower-speed applications.
