Key Features
- Dual NAND gate-based peripheral driver topology enabling logic-controlled high-current switching from standard TTL or CMOS outputs
- Built-in overcurrent protection safeguarding both the driver and connected loads such as relays and solenoids from fault conditions
- Gated input design allowing two logic signals to combinationally control each output, reducing discrete gate count in control circuits
- 4.75 V to 5.25 V regulated supply range ensuring compatibility with standard 5 V TTL logic systems without additional level shifting
- 8-pin SOIC (SOP) package with tube packaging providing a compact, low-profile SMT footprint for space-constrained PCBs
Applications
SN75452BPS is commonly used in industrial control boards to drive electromechanical loads such as relays, solenoids, and indicator lamps that require more current than a standard logic gate can supply. It also serves in printer head driver circuits and motor step indexers where NAND gate logic control of high-current outputs simplifies interface design. The overcurrent protection makes it well suited for unattended automation equipment where load fault conditions must not damage the driving circuitry.

Frequently Asked Questions
How many driver channels does SN75452BPS include, and what load types can each channel handle?
SN75452BPS includes 2 independent driver channels, each capable of sinking up to 300 mA of continuous collector current to switch electromechanical loads such as 5 V relays, 12 V solenoids (with an external supply), and LED indicator arrays. The high-current sink capability far exceeds the 8 mA drive limit of a standard TTL output, making it essential for inductive load switching.
What supply voltage range does SN75452BPS require, and how does overcurrent protection work?
SN75452BPS operates from a 4.75 V to 5.25 V supply, matching standard 5 V TTL logic power rails. The built-in overcurrent protection monitors output current on each channel and clamps conduction if the current exceeds the safe limit, preventing thermal damage to the device and reducing the risk of PCB trace burns in systems where output loads may short-circuit.
For a relay driver circuit needing NAND gate logic, why choose SN75452BPS over discrete transistors?
SN75452BPS integrates two NAND gate inputs per channel and a high-current Darlington output transistor with overcurrent protection into a single 8-pin SOIC package, replacing at least 6 discrete components per channel (2 logic gates, 1 transistor, 1 base resistor, 1 flyback diode, 1 current-limit resistor). This reduces BOM cost by roughly 40% and board area by more than 50% compared to a fully discrete relay driver design.
Is SN75452BPS the right replacement for SN75451BPS in an existing design, and what differs between the two?
SN75452BPS uses NAND gate inputs, while SN75451BPS uses AND gate inputs; all other specifications including the 300 mA output sink current, 4.75 V to 5.25 V supply, 8-pin SOIC package, and overcurrent protection remain identical. A drop-in replacement is possible if the upstream logic inversion is accounted for — adding an inverter stage or inverting the control signals in firmware resolves the polarity difference.
