Introduction
SN74HC245DBR - Bidirectional Bus Transceiver
Enabling bidirectional data transmission between two separate buses with high-speed performance and robust noise immunity.
Core Functions
- 8-bit bidirectional bus transceiver with tri-state outputs for flexible data flow control
- Wide operating voltage range (2V to 6V) compatible with both 3.3V and 5V logic systems
- High-speed data transfer up to 20MHz (typical) at 5V supply
- Direction control (DIR) and output enable (OE) pins for precise bus management
- Schmitt-trigger inputs for enhanced noise immunity in electrically noisy environments
- High output current capability (±25mA per pin) for driving multiple loads
Key Applications
Microcontroller Peripheral Expansion: Facilitates bidirectional data exchange between MCUs and external peripherals like LCD modules, keypads, and memory chips.
Logic Level Translation: Acts as voltage translator between 3.3V and 5V logic circuits while maintaining bidirectional data flow.
Bus Buffering & Isolation: Reduces load capacitance on main buses and isolates sensitive circuits from heavy-load peripherals.
Industrial Control Interfaces: Enhances signal integrity in PLC I/O expansion, sensor modules, and industrial bus extensions.
Consumer Electronics: Used in set-top boxes, appliances, and portable devices for control unit to peripheral communication.
Automotive Electronics: Supports data communication in infotainment systems, dashboards, and sensor hubs with reliable noise resistance.
