74LS53 DIP Expandable 4-Wide 2-Input AND-OR-Invert Gate IC (16-Pin TTL Logic IC)

The 74LS53 DIP Expandable 4-Wide 2-Input AND-OR-Invert Gate IC is a TTL logic integrated circuit that implements an expandable 4-wide 2-input AND-OR-Invert (AOI) logic function in a 16-pin Dual Inline Package (DIP). Built using Low Power Schottky (LS) TTL technology, it offers high-speed switching, low power consumption, and reliable digital logic performance.

The IC combines the outputs of four 2-input AND gates into an OR stage, followed by an inverted output, making it ideal for implementing complex Boolean logic with fewer external components. Its expandable architecture allows multiple devices to be cascaded for larger digital systems. The 74LS53 is widely used in combinational logic, control systems, decoding circuits, industrial automation, embedded systems, and digital control applications.
