CD40014 IC is a direct replacement for the 74C14/54C14 IC. CD40014 is a general purpose Hex Schmitt Trigger Offering Positive and negative threshold voltages, Vt and Vt-, which shows very low variation with temperature (typically 0.0005V/Deg C at VDD = 10V) and guaranteed hysteresis, Vt to Vt- >= 0.2 VDD. Outputs are fully buffered for highest noise immunity.Datasheet:-CD40014 Datasheet

CD4010 Hex Buffer/Converters may be used as CMOS to TTL or DTL logic-level converters or CMOS high-sink-current drivers.The CD4010 types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix).
