• Wide operating voltage range: VCC = 2 V to 5.5 V
• Pin and function compatible with 74HC540

Benefits:

• Improved system performance due to high-speed operation.
• Reduced power consumption leading to energy efficiency and longer battery life in portable devices.
• Enhanced noise immunity ensures reliable operation in noisy environments.
• Easy integration with other TTL and CMOS devices due to compatibility.
• Simplified system design due to balanced propagation delays.
• Wide operating voltage allows flexibility in system design.

The TC74VHC540F(K,F) features octal buffers with three-state outputs. When the output enable (OE) is low, the device passes data from the inputs to the outputs. When OE is high, the outputs are forced to a high-impedance state, allowing multiple devices to share the same bus. It operates across a wide temperature range, making it suitable for various industrial and commercial applications. The device is supplied in a SOP package.
