The SN74LVT162240DGG is a low-voltage, 4-channel inverting buffer from Texas Instruments, designed for 3.3V systems. It features 3-State outputs with 12mA source and sink capability. Operating from 2.7V to 3.6V, this buffer is ideal for bus-oriented applications, signal conditioning, and driving capacitive loads in low-voltage designs. Its 48-TFSOP package is suitable for space-constrained applications, while the -40°C to 85°C temperature range ensures reliable performance in industrial environments.
- Low-Voltage Operation (2.7V to 3.6V): Compatible with 3.3V logic, reducing power consumption.
- 4 Channels in One Package: Saves board space and simplifies layout for multi-line buffering.
- 3-State Outputs: Enables bus multiplexing and system isolation, preventing data contention.
- TTL-Compatible Inputs: Simplifies interfacing with standard 3.3V TTL logic families.
3.3V Bus Line Driving
Use the SN74LVT162240DGG to drive high-capacitance bus lines in 3.3V systems. Its 12mA drive capability ensures fast signal transitions and maintains signal integrity on PCB traces.
Memory Address Buffering
Buffer address lines from a 3.3V CPU to multiple memory banks. The inverting function can simplify PCB routing, while 3-State outputs allow for easy bank selection.
Signal Inversion in Low-Voltage Logic
Employ this buffer to invert logic signals in 3.3V digital systems. The TTL-compatible inputs ensure reliable operation with standard 3.3V logic.
Peripheral Interface Isolation
Isolate a 3.3V microcontroller from peripheral devices. The 3-State outputs can be placed in high-impedance mode to disconnect the peripheral, preventing bus contention.
Industrial Control Logic
In industrial control panels, use this buffer to interface between a 3.3V PLC and other subsystems. Its wide operating temperature range (-40°C to 85°C) ensures reliable operation in harsh environments.
Telecommunications Equipment
Use in telecom equipment for buffering control signals between line cards and backplane. The low-voltage operation reduces power consumption in dense systems.
