Texas Instruments CD74HC126E Buffers, Drivers, Receivers and Transceivers Overview
Quad buffer with 3-state outputs, featuring CMOS technology for high-speed logic operation. This component offers four independent buffer elements, each with one input and one output, supporting a wide operating temperature range from -55°C to 125°C. It operates with supply voltages between 2V and 6V, delivering ±7.8mA of output current.
The buffer is non-inverting and mounts via through-hole termination in a PDIP package with gold contact plating.
