The SN74LVTH126DBR from Texas Instruments is a high-performance quadruple non-inverting bus buffer featuring 3-State outputs. Operating from a 2.7V to 3.6V supply, it is ideal for 3.3V systems requiring high drive capability, with 32mA source and 64mA sink current. The 4 channels come in a compact 14-SSOP package, making it suitable for space-constrained designs. Its low-voltage operation and high-speed performance make it a reliable choice for bus interfacing, signal buffering, and memory driving applications.
- High Drive Current (64mA Sink): Can drive heavily loaded buses and long traces without signal degradation.
- 3-State Outputs: Enables bus multiplexing and prevents bus contention in multi-device systems.
- Wide 2.7V to 3.6V Supply Range: Compatible with standard 3.3V logic, simplifying power design.
- Fast Propagation Delay: Suitable for high-speed data transmission in communication systems.
High-Speed Bus Interfacing
Use the SN74LVTH126DBR to buffer address and data lines between a 3.3V microcontroller and high-capacitance memory or peripheral buses. The 3-State outputs allow multiple devices to share the same bus without contention.
Signal Buffering for Backplane Drivers
In telecom and networking equipment, this buffer can drive long backplane traces. Its high drive current (64mA sink) ensures signal integrity over extended distances.
Level Shifting in Mixed-Voltage Systems
While optimized for 3.3V, it can interface between 2.7V and 3.6V logic domains, providing a clean buffer stage between different low-voltage sections of a design.
Memory Address/Data Latching
Use the 3-State outputs to isolate memory banks during read/write cycles. The non-inverting nature preserves address integrity, while the output enable control simplifies bank selection.
Industrial Control I/O Expansion
In PLCs and industrial controllers, this buffer can drive multiple indicator LEDs or relay driver inputs. The 32mA source capability is sufficient for many optocoupler inputs.
Test and Measurement Equipment
For automated test equipment, the SN74LVTH126DBR can route test signals to different measurement points. The fast propagation delay and 3-State control enable efficient signal routing.
