The internal circuits arecomposed of 3-stages (HC4049A) or 2-stages (HC4050A) ofinvertaers, which provided high noise immunity and stableoutput.Input protection circuits are different from those of other highspeed CMOS IC’s. They eliminate the diodes on the VCC sidethus providing of logic-level conversion from high-level volagesup to 15 V to low-level voltages.They are useful for battery back up circuits, because inputvoltage can be applied on IC’s which are not biased by VCC.Features• High speed: tpd = 9 ns (typ.) at VCC = 5 V• Low power dissipation: ICC = 1 μA (max) at Ta = 25°C• High noise immunity: VNIH = VNIL = 28% VCC (min)• Output Drive Capability: 15 LSTTL loads• Symmetrical output impedance: |IOH| = IOL = 6 mA (min)• Balanced propagation delays: tpLH ∼− tpHL• Wide operating voltage range: VCC (opr) = 2 V to 6 V• Pin and function compatible with 4049B/4050BNote: xxxFN (JEDEC SOP) is not available inJapan.TC74HC4049AP, TC74HC4050APTC74HC4049AF, TC74HC4050AFTC74HC4049AFN, TC74HC4050AFNTC74HC4049AFT, TC74HC4050AFTWeightDIP16-P-300-2.54A: 1.00 g (typ.)SOP16-P-300-1.27A: 0.18 g (typ.)SOL16-P-150-1.27: 0.13 g (typ.)TSSOP16-P-0044-0.65A: 0.06 g (typ.)
