The 74LCX2244MTC is a dual-channel non-inverting buffer from Fairchild Semiconductor's 74LCX family. It operates from 2V to 3.6V, providing 12mA source and sink current per channel. The 3-State outputs enable bus-oriented applications, while the low-power CMOS design minimizes heat generation. Housed in a compact 20-TSSOP package, it is ideal for buffering signals in networking equipment, portable devices, and industrial control systems.
- Low-Voltage Operation (2V-3.6V): Compatible with modern 3.3V and 2.5V logic, reducing power consumption.
- 3-State Outputs: Allows multiple devices to share a bus safely, simplifying board design.
- High Output Current (12mA): Drives LEDs and low-impedance loads without additional buffers.
- Wide Temperature Range (-40°C to 85°C): Suitable for industrial and automotive environments.
3.3V Bus Interfacing
Use the 74LCX2244MTC to buffer address or data lines between a 3.3V microcontroller and peripheral devices. Its 3-State outputs allow multiple devices to share the same bus without contention.
Signal Buffering for High-Speed Logic
In mixed-voltage systems, this buffer isolates sensitive logic inputs from noisy output stages. The 74LCX family's low propagation delay ensures minimal signal degradation.
Level Shifting (3.3V to 2.5V)
With a supply range down to 2V, this buffer can translate 3.3V logic signals to lower-voltage domains, enabling communication with 2.5V or 1.8V ASICs and FPGAs.
Driving LED Arrays
Each output can sink or source 12mA, sufficient to drive standard LEDs with current-limiting resistors. The 3-State feature allows multiplexing of LED groups.
Memory Address Buffering
In embedded systems, buffer address lines to SRAM or flash memory to reduce capacitive loading on the main controller, improving signal integrity and timing margins.
Industrial Sensor Interfaces
Buffer digital sensor outputs in industrial control panels. The -40°C to 85°C temperature range ensures reliable operation in harsh environments.
