The MC14049B Hex Inverter/Buffer and MC14050B Noninverting. Hex Buffer are constructed with MOS P Channel and N Channel enhancement mode paralleled standard gates or by the MC14049 or MC14050 buffers. The clock input circuit (pin 7) has Schmitt trigger shaping such that proper clocking will occur The MC14049B Hex Inverter/Buffer and MC14050B Noninverting Hex Buffer are constructed with MOS P-Channel and N-Channel enhancement mode devices R2 4 RED 536 ll. 1k 15 T13/4 LED r_ 1/6. : MOMENTARY MC14049 .
