Buffer/Converter 6-CH Inverting CMOS 16-Pin SOL

The TC74HC4049 series is high speed CMOS HEX BUFFERs fabricated with silicon gate C²MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The TC74HC4049 is an inverting buffer. The internal circuits are composed of 3-stages (HC4049), which provided high noise immunity and stable output. Input protection circuits are different from those of other high speed CMOS IC’s. They eliminate the diodes on the VCC side thus providing of logic-level conversion from high-level voltages up to 15 V to low-level voltages. They are useful for battery back up circuits, because input voltage can be applied on IC’s which are not biased by VCC.

• 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 to 6 V
• Pin and function compatible with 4049B
