74LS07 Hex Buffer with High Voltage Open-Collector Outputs – Datasheet

74LS07 Hex Buffer/driver features high-voltage open-collector outputs to interface with high-level circuits or for driving high-current loads. They are also characterized for their usage as buffers for driving TTL inputs.

A Hex buffer is a basic logic gate that passes its input, unchanged, to its output. Its behavior is the opposite of a NOT gate. The main purpose of a buffer is to regenerate the input, usually using a strong high and a strong low. A buffer has one input and one output; its output is always equal to its input. Buffers are also used to increase the propagation delay of circuits by driving the large capacitive loads.
