Description

2.

The TC74HC4049AFT and TC74HC4050AFT are high speed CMOS HEX BUFFERs fabricated with silicon gate C2MOS technology.

Features

  • (1) Wide operating temperature range: Topr = -40 to 125.
  • (Note 1) (2) High speed: tpd = 9 ns (typ. ) at VCC = 5.0 V (3) Low power dissipation: ICC = 1.0 µA (max) at Ta = 25.
  • (4) High noise immunity: VNIH = VNIL = 28 % VCC (min) (5) Symmetrical Output impedance: |IOH| = IOL = 6 mA (min) (6) Balanced propagation delays: tPLH ≈ tPHL (7) Wide operating voltage range: VCC(opr) = 2.0 V to 6.0 V (8) Power-down protection is provided on all inputs. Note 1: Operating Range spec of Topr = -40.

Functional Description • Hex Buffer TC74HC4049AFT: HEX BUFFER/CONVERTER (INVERTING) TC74HC4050AFT: HEX BUFFER/CONVERTER 2. General The TC74HC4049AFT and TC74HC4050AFT are 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 TC74HC4049AFT is an inverting buffer, while the TC74HC4050AFT is a non-inverting buffer. The internal circuits are composed of 3-stages (TC74HC4049AFT) or 2-stages (TC74HC4050AFT) of inverter, which provided high noise immunity and stable output.
