The TC74VHC244FK is an advanced high-speed CMOS octal buffer fabricated with silicon gate CMOS technology. It achieves high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. This device is an octal buffer/line driver designed for high-speed memory systems, address decoders, clock drivers, and other bus-oriented applications.

Applications:

• High-speed memory systems
• Address decoders
• Clock drivers
• Bus-oriented applications
• Microprocessor systems
• Data transmission

Features:

• High-speed: tpd = 4.1 ns (typ.) at VCC = 5 V
• Low power dissipation: ICC = 4 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 = 2 V to 5.5 V
• Pin and function compatible with 74LS244
