Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the output enable pins?

The output enable pins control the three-state condition of the buffers, allowing them to drive the bus or enter a high-impedance state.

Is this component compatible with CMOS inputs?

No, the SN74LS126AD is designed for TTL input levels and may not interface correctly with standard CMOS inputs without level shifting.
