The MM74HC125MTCXTSSOP14 is a Quad 3-STATE Buffer from Fairchild/ON Semiconductor. This device contains four independent buffers, each with its own output enable (OE) input. When the OE input is LOW, the buffer passes the input signal to the output. When the OE input is HIGH, the output is in a high-impedance (3-STATE) state, effectively disconnecting the buffer from the output line. This allows multiple devices to share a common bus.

Applications

• Memory Address Drivers
• Bus Interface
• Logic Level Shifters
• Microprocessor Systems
• Data Transmission

Features

• High speed: tpd = 13 ns (typical) at VCC = 5V
• Low power dissipation: ICC = 4 μA (maximum) at VCC = 5V
• Wide operating voltage range: 2V to 6V
• High noise immunity: NIM = 30 % VCC, NIL = 30 % VCC
• 3-STATE Outputs: Provides high impedance state for bus isolation

Benefits

• Fast switching speeds for medium-performance applications
• Very low power consumption for portable applications
• Versatile operating voltage for different system requirements
• High noise immunity for reliable operation in noisy environments
• Allows multiple devices to share a common bus, reducing component count

Additional Details

The MM74HC125MTCXTSSOP14 is housed in a TSSOP (Thin Shrink Small Outline Package) with 14 pins, making it suitable for surface-mount applications where board space is limited. The operating temperature range is -40°C to +85°C. The 3-STATE outputs are particularly useful in bus-oriented systems, allowing multiple devices to drive the bus without contention. The HC family offers a good balance of speed and power consumption.
