Key Features
- Built-in overcurrent protection safeguards both the driver and connected loads from damage during fault conditions
- Open-collector output structure allows wired-AND connections and direct driving of loads referenced to voltages higher than the logic supply
- AND-gate input logic with 2 inputs per channel provides on-board gating to eliminate external discrete gates in control circuits
- High-speed switching and high sink current capability enable reliable driving of relays, solenoids, and indicator lamps directly from TTL/CMOS logic
Applications
The SN75451BD is widely used in industrial control systems, printers, and motor drive circuits where logic-level signals must switch power loads such as relays, solenoids, and indicator lamps. Its AND-gate input structure also makes it useful in enable-gated driver applications, allowing two control signals to jointly activate a high-current output without external glue logic.

Frequently Asked Questions
What type of output does the SN75451BD have?
The SN75451BD has open-collector outputs, which means the output transistor can only sink current to ground. An external pull-up resistor or load connected to a supply voltage is required, allowing the driver to switch loads operating at voltages different from the logic supply.
What is the input logic structure of the SN75451BD?
Each of the two driver channels has a 2-input AND gate at its input stage. The output is active only when both inputs are logic high simultaneously, providing on-chip enable gating and eliminating the need for a separate AND gate in many control circuit designs.
Does the SN75451BD have overcurrent protection?
Yes, the SN75451BD includes built-in overcurrent protection on each output channel. This internal protection limits the output current during fault conditions such as shorted loads, helping to prevent permanent damage to the device and the connected peripheral.
What types of loads can the SN75451BD drive?
The device can drive inductive loads such as relays, solenoids, and stepper motor windings, as well as resistive loads like indicator lamps and heater elements. The open-collector output supports wired-AND bus configurations and enables connection to loads referenced to supplies above the logic rail.
What package is the SN75451BD available in?
The SN75451BD is housed in an 8-pin Small Outline IC (SOIC) package with JESD-30 code R-PDSO-G8 and RoHS-compliant JESD-609 code e4. This package is compatible with standard automated PCB assembly processes and is widely stocked by distributors worldwide.
