SN74HC240N (74HC240)
This content will be shared across all product pages.
Description:
The SN74HC240N is an octal buffer/driver with 3-state outputs. This device is part of the 74HC family of high-speed CMOS logic integrated circuits. It contains eight non-inverting buffers and features two enable inputs, which allow for easy control of the data flow. The 3-state outputs enable multiple devices to share the same output lines, making it ideal for bus-oriented systems.
