This electronic component is a dual Schmitt trigger buffer manufactured by Texas Instruments. It is part of their Logic - Buffers, Drivers, Receivers, Transceivers series of parts and is commonly used in digital logic circuits to provide buffering, level conversion, and fan-out.This particular part has a power supply voltage range of 1.65V to 5.5V, and an output current of +/- 10mA to +/- 24mA. It is a Schmitt trigger input buffer, meaning the input logic thresholds (the logic levels at which the output signal will change) are adjustable, which is useful for dealing with noise, slow input transitions, and input signal levels. This component also has an open drain output, which allows for both push-pull and open drain operation. It is also designed to be pin and function compatible with the SN54LSXX, SN54SXX, and SN74LSXX series of parts.
