Schmitt logic circuits are often used to design pulse generators. Since the two thresholds (1/3 Vcc & 2/3 Vcc) are widely separated, they make a very good Schmitt trigger. 76 0 obj <>/Filter/FlateDecode/ID[<1486DCB1440655A84592B1545D0F4EAA><7D8190553DE48B49A08ED8D3C456B208>]/Index[57 46]/Info 56 0 R/Length 95/Prev 69884/Root 58 0 R/Size 103/Type/XRef/W[1 2 1]>>stream CMOS Schmitt Waveform Generator. h�b```f``�g`a`�1b�g@ ~�+s`\�f�fZ#k�����L���dƋg]q��%)R�J�K=3��:�2:���10����Xl�)^�I,!� ,�,)U�PqSrj|1���}��~�u5 c`�� ����%�~A�� �)m It is an active circuit which converts an analog input signal to a digital output signal. %%EOF Hex Schmitt-Trigger Inverter High−Performance Silicon−Gate CMOS The MC74HC14A is identical in pinout to the LS14, LS04 and the HC04.
