The 74VCX162244MTDX is a 16-bit non-inverting buffer from Fairchild Semiconductor, optimized for ultra-low-voltage applications. Operating from 1.2V to 3.6V, it provides four 4-bit channels with 3-State outputs, each delivering 12mA drive. This makes it perfect for interfacing low-voltage processors with peripherals in portable and battery-powered electronics, all in a compact 48-TFSOP package.
- Ultra-Low 1.2V Operation: Enables direct interfacing with the latest low-voltage logic and processors.
- Balanced 12mA Drive: Suitable for moderate-speed signal buffering without excessive power consumption.
- 3-State Outputs: Allows multiple peripherals to share a common data bus safely.
- Wide Supply Range (1.2V-3.6V): Provides design flexibility across different voltage domains.
Low-Voltage FPGA Configuration
Buffer configuration data lines from a 1.2V FPGA to 3.3V flash memory. The 1.2V minimum supply ensures compatibility with the latest low-power FPGAs.
Smartphone Application Processor I/O
Use the 74VCX162244MTDX to buffer camera sensor or display interface signals, where 1.8V/2.5V logic levels are common. The 12mA drive is sufficient for short PCB traces.
Battery-Powered IoT Devices
In wearables, the ultra-low voltage operation (down to 1.2V) minimizes power draw while buffering sensor data to the main MCU.
Memory Card Interface
Drive SD/eMMC card signals with 3-State outputs to allow multiple card slots to share a single controller bus.
Mixed-Voltage Industrial Sensors
Interface 1.8V logic sensors to a 3.3V PLC input module, providing a non-inverting buffer with controlled output slew.
Portable Medical Devices
Buffer ECG or glucose monitor signals in low-power devices, ensuring signal integrity while operating from a single 1.8V battery.
