The TC74HC241AF is an octal buffer and line driver from Toshiba Semiconductor and Storage, featuring three-state outputs. This device is designed to improve the performance and density of three-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. It is fabricated with silicon gate C2MOS technology.

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented receivers
• Bus-oriented transmitters
• Microprocessor systems
• Logic buffers

Features

• High-speed operation: tpd = 13 ns (typ.) at VCC = 5V
• High output current: IOH = -6 mA, IOL = 6 mA
• Wide operating voltage range: VCC = 2 to 6 V
• Low input current: 1 μA (max)
• Three-state outputs
• Pin and function compatible with 74HC241
• Non-inverting outputs

Benefits

• Improved system performance due to high-speed operation.
• Ability to drive heavily loaded buses and transmission lines because of high output current.
• Flexibility in power supply design due to wide operating voltage range.
• Reduced loading on the input signal source because of low input current.
• Enables easy data busing through the three-state outputs.
• Simplified system design and reduced cost due to pin compatibility with industry-standard 74HC241 devices.

Additional Details

The TC74HC241AF consists of non-inverting three-state buffers. It has two output enables, which are active low. When either of the output enables is high, the outputs are in a high-impedance state. The device is supplied in a SOP20 package. The operating temperature ranges from -40°C to +85°C.
