Product Overview: CD54HC640F3A from Texas Instruments

The CD54HC640F3A is a high-performance integrated circuit designed and manufactured by Texas Instruments, a leader in the semiconductor industry. This IC is a part of the high-speed CMOS logic family and is known for its robustness and reliability in various applications. The device features an octal bus transceiver with 3-state outputs, making it an ideal choice for bidirectional communication between data buses.

Key Features

• Logic Type: Octal Bus Transceiver
• Logic Family: HC
• Operating Voltage Range: 2V to 6V
• Output Drive Capability: 15mA at 5V
• 3-State Outputs: Facilitate bus buffering
