Frequently Asked Questions
What is the output drive current of the SN74ABT125PWE4?
The SN74ABT125PWE4 provides a maximum output low current (IOL) of 64mA, making it capable of driving heavy bus loads and multiple TTL/CMOS inputs simultaneously in high-speed digital systems.
How does the 3-state output work on the SN74ABT125PWE4?
The 3-state outputs are controlled by an active-low enable (OE) pin. When OE is high, all four output buffers enter the high-impedance state, effectively disconnecting them from the bus and allowing other devices to drive the shared bus lines.
What logic family does the SN74ABT125PWE4 belong to?
The SN74ABT125PWE4 belongs to the ABT (Advanced BiCMOS Technology) logic family, which offers a combination of high-speed operation, low power consumption, and the ability to drive large bus capacitive loads efficiently.
What package is used for the SN74ABT125PWE4?
The SN74ABT125PWE4 comes in a 14-pin TSSOP (Thin Shrink Small Outline Package), a compact surface-mount package with fine pitch leads suitable for high-density PCB assemblies in modern electronic equipment.
