Introduction
SN74LVC244APWR - Octal Buffer/Line Driver
High-performance octal (8-channel) buffer/line driver manufactured by Texas Instruments (TI). Part of the LVC (Low-Voltage CMOS) family, designed to amplify and buffer digital signals in low-voltage systems with signal isolation, fan-out expansion, and voltage-level translation capabilities.
Core Functions
- Octal Unidirectional Buffering
- 8 independent buffer channels maintain signal integrity from input to output
- Unidirectional design prevents unintended feedback in digital systems
- High-Speed Signal Handling
- 3.8 ns typical propagation delay supports systems up to 125 MHz
- Maintains signal integrity at high switching speeds
- Voltage Compatibility & Level Translation
- 1.65V to 3.6V operating range compatible with LVCMOS logic families
- Translates signals between different voltage domains
- High Fan-Out Capability
- 24 mA source/sink current per output drives multiple loads
- Eliminates signal attenuation in complex interconnects
- Output Enable Control
- Two independent active-low output enable pins (OE1 and OE2)
- High-impedance state when disabled for bus sharing and power management
- ESD Protection
- ±2 kV human-body model and ±500 V machine model protection
- Enhanced reliability for handling and system operation
Typical Applications
Microprocessor/MCU Interfaces
Buffers address, data, or control signals between microprocessors/microcontrollers and peripherals. Example: Buffering address bus from 3.3V MCU to interface with 1.8V SRAM.
Data Bus Expansion
Expands fan-out of data buses in industrial controllers, preventing signal loading on main bus.
Voltage Level Translation
Facilitates communication between components at different voltage levels (e.g., 3.3V USB to 1.8V Bluetooth).
Memory Systems
Buffers address and control signals in memory interfaces to maintain data integrity during high-speed operations.
Industrial & Automotive Electronics
Buffers control signals in automation systems and interfaces MCU signals with higher-current components in automotive applications.
Consumer Electronics
Buffers signals between SoCs and peripherals in smartphones, tablets, and set-top boxes.
Key Advantages
- Compact Integration: 20-pin TSSOP package saves PCB space
- Energy Efficiency: Low-voltage operation minimizes power consumption
- Design Flexibility: Independent enable pins support dynamic system reconfiguration
