About this product
The 74240 is an octal 3-state buffer and line driver for TTL bus applications. Its outputs are inverting, so each output is the complement of its input. It is used to drive bus lines, buffer microcontroller ports and interface logic to memory or peripheral boards in 5 V systems. Available in a PDIP-20 package.

How is the 74240 different from the 74244?
The 74240 inverts data, while the 74244 passes data without inversion. Both are octal buffers with 3-state outputs, so check the logic polarity before swapping one for the other.
What should I do with the enable inputs of the 74240?
The enable inputs are active-low and each controls a group of four outputs. Do not leave them floating; tie them to a defined level from your control logic.
