The 3-state outputs let you wire-OR multiple buffers onto a bus; when the output-enable pin is low, the output goes high-impedance and the bus floats clean. The 74ABT series is still a standard logic family in TI's catalog, so you can expect consistent supply through distribution.","metaTitle":"SN74ABT126PW 74ABT Buffer, Non-Inverting, 4.5V-5.5V","metaDescription":"TI SN74ABT126PW 74ABT quad buffer with 3-state outputs, 32/64 mA drive, -40°C to 85°C.
