ON Semiconductor MC74VHC1G125DFT1 Single Bus Buffer Gate with 3-State Output

The MC74VHC1G125DFT1 is a high-speed CMOS single bus buffer gate fabricated with silicon gate CMOS technology. Designed by ON Semiconductor, this device boasts a 3-state output which is capable of driving up to 15 LSTTL loads. The 3-state function allows for connection to a bus-organized system and, when disabled, the output effectively becomes an open circuit. This feature is particularly useful in multiplexing applications where output connectivity must be controlled.

With its advanced design, the MC74VHC1G125DFT1 achieves high-speed operation while maintaining the CMOS low power dissipation. It is compatible with LSTTL outputs, and this buffer gate has an input protection structure that ensures that if the input voltage exceeds the supply voltage, there will be no current flow from the input to the device. This level of input protection helps to prevent damage to the component when it is subjected to high static voltages or electric fields.

The device is housed in a small SC-88A surface-mount package, making it ideal for space-constrained applications. It operates over a broad voltage range of 2.0V to 5.5V and is fully specified for partial power-down applications using Ioff. The Ioff circuitry ensures no damaging current backflow to the device when it is powered down.

Key features of the MC74VHC1G125DFT1 include:

• High-Speed CMOS Technology
• 3-State Output for Bus Organized Systems
• High Noise Immunity Characteristic of CMOS Devices
• Input Protection from Static Discharge
• Low Power Dissipation
• Wide Operating Voltage Range: 2.0V to 5.5V
• Support for Partial Power-Down Mode Operation
• Compact SC-88A Packaging

The ON Semiconductor MC74VHC1G125DFT1 is an ideal choice for interfacing with high-speed CMOS systems. Its robust design and versatile features make it a reliable component for designers looking to create efficient and high-performance electronic circuits. Whether used in data transmission, memory address driving, or as a temporary data storage element, this buffer gate provides a combination of speed, low power consumption, and functional design to meet a wide range of application needs.
