SN74HC245N BUS TRANSCEIVER 8 BIT NON INVERTING 2 - 26V 20 PIN
Description:
- Texas Instruments' SN74HC245N is a high-speed CMOS 8-bit non-inverting bus transceiver that allows for bidirectional communication between data buses.
- The SN74HC245N bus transceiver supports bidirectional data transfer between busses.
- It has a direction control (DIR) input that determines the direction of data flow, and an enable (OE) input that controls the three-state output.
- When OE is low, data transmission is enabled, whereas when OE is high, all outputs become high impedance, thereby removing the transceiver from the bus.
- 8-Bit Bidirectional Data transmission: Enables data transmission between two buses with an 8-bit data width, making it appropriate for a variety of data routing and communication systems.
- Non-inverting Outputs: The output keeps the inputs' logic state, maintaining data integrity without inversion.
- Wide Operating Voltage Range: Operates at voltages ranging from 2V to 6V, ensuring compatibility with various logic levels.
- 3-State Outputs: Three-state control allows the outputs to be set to a high impedance state, which is suitable for bus-oriented systems where several devices share common lines.
- TTL-Compatible Inputs and Outputs: Provides simple integration with TTL logic circuits, increasing the adaptability of the system.
- Low Power Consumption: Designed to consume as little power as possible, making it perfect for low-power and battery-powered applications.
