Product Details

The 74VHC240FT and 74VHC244FT are advanced high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The 74VHC240FT is an inverting 3-state buffer having two active-low output enables. The 74VHC244FT is a non-inverting 3-state buffer, and has two active-low output enables. These devices are designed to be used with 3-state memory address drivers, etc. An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.

Wide operating temperature range: Topr = -40 to 125 
High speed: tpd = 3.9 ns (typ.) at VCC = 5 V
Low power dissipation: ICC = 4.0 μA (max) at Ta = 25 
High noise immunity: VNIH = VNIL = 28 % VCC (min)
Power down protection is provided on all inputs.
Balanced propagation delays: tPLH ≈ tPHL
Wide operating voltage range: VCC(opr) = 2.0 V to 5.5 V
Low noise: VOLP = 0.8 V (max)
Pin and function compatible with the 74 series (AC/HC/AHC/LV etc.) 240 or 244 type
