Overview of SN74ABT126DB

The SN74ABT126DB is a high-performance quadruple bus buffer gate from Texas Instruments, designed to provide state-of-the-art functionality for bus interface or signal buffering applications. This integrated circuit is part of the ABT family, which is known for its advanced biCMOS technology that combines the low power consumption of CMOS with the high speed of bipolar transistors.

Key Features

• Logic Type: Quadruple Bus Buffer Gates with 3-State Outputs
• Operating Voltage: Ranges from 4.5V to 5.5V, making it suitable for 5V systems.
• Output Drive Capability: Capable of driving up to 64mA at 5V, which allows for driving heavy loads or multiple devices.
• Speed: Propagation delay times significantly lower than ABT devices, facilitating faster signal processing.
• Package: Available in a 14-pin SSOP (Shrink Small-Outline Package), which is ideal for space-constrained applications.

Product Applications

The SN74ABT126DB is versatile and can be used in a wide array of applications, including:

• Bus Interface or Termination Networks
• Signal Buffering for Data Transmission
