The SN74BCT760NS from Texas Instruments is a dual non-inverting buffer with open collector outputs. Operating from 4.5V to 5.5V, it can sink up to 64mA, making it suitable for driving loads like LEDs, relays, and wired-OR buses. Housed in a 20-SOIC package, it is ideal for industrial controls, I2C buffering, and level shifting applications where open collector topology is required.
- Open Collector Outputs: Enable wired-OR logic and level shifting to higher voltages.
- 64mA Sink Current: Drives high-current loads directly without external transistors.
- 74BCT Family: Combines high-speed TTL performance with low power consumption.
- Standard 5V Operation: Compatible with legacy TTL systems and modern 5V microcontrollers.
Wired-OR Interrupt Lines
In microcontroller systems, use the SN74BCT760NS to connect multiple interrupt sources. The open collector outputs allow any device to pull the line low, simplifying interrupt management.
Level Shifting to Higher Voltages
With open collector outputs and external pull-up resistors, this buffer can shift 5V logic to 12V or 24V for industrial sensors, enabling direct interface with PLCs.
LED and Relay Driving
The 64mA sink capability makes it ideal for driving LEDs, relays, or optocouplers directly from logic signals, reducing the need for external transistor drivers.
I2C Bus Buffering
For I2C buses with many devices, this buffer can isolate capacitive loads. The open collector outputs match I2C's wired-AND architecture, improving signal integrity.
Power Supply Sequencing
In server systems, use this buffer to control power-good signals. Open collector outputs allow multiple power supplies to share a common status line.
Automotive Indicator Control
In automotive ECUs, the 0°C to 70°C range suits cabin electronics. Use it to drive indicator lamps with high current sinking.
