SN75107BN

Introduction

The SN75107BN is a three-pin, DIP-type TTL line driver designed for operation in the low-voltage (3.3 to 5 volts) TTL logic family. It features a low output power and high current (up to 2 A) capability as well as a very low offset voltage and low on-resistance. SN75107BN can be used as an interface between devices with different voltage requirements, such as TTL, CMOS, RS-232 and others. The SN75107BN is also an excellent choice for driving loads such as relays, motors, LEDs, and other DC devices.

Application Fields

The SN75107BN can be used in a variety of applications, such as:

• Industrial control circuits
• Automation circuits
• Power supplies
• High speed and low current applications
• LED lighting circuits
• I/O interfaces for microcontrollers

Working Principle

The SN75107BN is a three-pin, DIP-type TTL line driver. It features a low output power and high current (up to 2 A) capability. The SN75107BN has two inputs: an input voltage (VIN) and an active high enable (EN). VIN is a TTL logic level signal, while EN is a TTL logic signal that controls the output. When EN is high, the output (OUT) is active. When EN is low, the output is disabled and OUT is held low. It is possible to use the SN75107BN in “open drain” mode by leaving EN unconnected, or in “tristate” mode by connecting EN to VDD.

The SN75107BN is designed to work in the low-voltage (3.3 to 5 volts) TTL logic family. It has a very low offset voltage, so it can drive loads directly from the logic signal and draw no additional current. It also has a low on-resistance, which reduces power dissipation, and a wide operating temperature range (-40°C to 85°C).

Moreover, the three pins require just one external component to ensure proper operation, making it very easy to design and build reliable circuits. It also comes in small, low-profile DIP packages that are ideal for space-constrained applications.

Conclusion

The SN75107BN is an ideal interface for devices with different voltage requirements, such as TTL, CMOS, RS-232 and other logic families. It can also be used to drive loads such as relays, motors, LEDs, and other DC devices. The SN75107BN is a three-pin, DIP-type TTL line driver featuring a low output power and high current capability, a low offset voltage, and low on-resistance. It requires only one external component for proper operation, and its small size and low-profile DIP packages make it suitable for use in space-constrained applications.
