Texas Instruments SN74HCS541/SN74HCS541-Q1 Buffer & Line Drivers

Texas Instruments SN74HCS541/SN74HCS541-Q1 Octal Buffers and Line Drivers contain eight buffers with 3-state outputs and Schmitt-trigger inputs. The active-low output-enable pins (OE1, OE2) of the Texas Instruments SN74HCS541/SN74HCS541-Q1 control all eight channels and are configured such that both must be low for the outputs to be active.
