TEXAS INSTRUMENTS  SN74LS14DR  非门, 施密特触发, 6输入, 8 mA, 4.75V至5.25V, SOIC-14

The is a Hex Schmitt-trigger Inverter each circuit functions as an inverter, but because of the Schmitt action, it has different input threshold levels for positive-going VT+ and negative-going VT- signals. The circuits are temperature compensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals.
