74LS173 DIP-16 Quad D-Type Flip-Flop IC (3-State Outputs, TTL, 5V)

Description -

The 74LS173 DIP is a TTL logic integrated circuit containing four D-type flip-flops with 3-state outputs in a 16-pin Dual Inline Package (DIP). It belongs to the 74LS Low Power Schottky logic family and is designed for data storage, bus interfacing, register applications, and digital control systems.

The device stores data on the rising edge of the clock and features 3-state outputs, allowing multiple devices to share a common data bus without contention. It also includes dual data-enable inputs for controlled data loading and an asynchronous master reset for immediate clearing of all stored data.
