The 74FCT244CTSOG is a dual non-inverting buffer from IDT, designed for 5V applications. It operates from 4.75V to 5.25V with output currents of 15mA (source) and 64mA (sink). The 3-State outputs support bus sharing, and the 20-SOIC package offers a standard footprint. This buffer is well-suited for bus interfacing, memory control, and industrial sensor buffering where reliable performance is required.
- Standard SOIC Package: 7.50mm width is widely used and easy to solder.
- Non-Inverting Buffer: Preserves signal integrity without inversion.
- High Drive Current (64mA Sink): Drives heavy loads reliably.
- 3-State Outputs: Enables bus multiplexing and reduces power.
Standard Bus Interfacing
The 74FCT244CTSOG is ideal for buffering data and address buses in 5V systems. Its 3-State outputs allow multiple devices to share the bus without conflict.
Microprocessor Peripheral Buffering
Buffer control signals from a microprocessor to peripherals like UARTs, timers, or memory. The non-inverting function preserves signal polarity, simplifying firmware.
Level Shifting in Mixed-Voltage Designs
Interface 5V logic to 3.3V devices using pull-up resistors on the outputs. The buffer's high sink current ensures reliable low-level signaling.
Industrial Sensor Interfacing
Buffer sensor output signals in industrial control systems. The -40°C to 85°C temperature range ensures reliable operation in harsh environments.
Memory Read/Write Buffering
Buffer read/write control signals to memory devices. The 3-State outputs allow the control lines to be tri-stated during bus idle periods.
Driving Multiple LED Indicators
Use the buffer to drive multiple LEDs or indicator lamps. The 64mA sink current can directly drive LEDs without additional driver ICs.
