74173 IC 4-Bit D-Type Registers With 3-State Outputs DIP-16

The 74173 IC 4-Bit D-Type Register with 3-State Outputs, designated as SN74LS173N and manufactured by XBLW, is a high-performance monolithic integrated circuit comprising four D-type flip-flops with totem-pole 3-state outputs, optimized for direct interfacing with system buses in digital logic applications. This device supports two operational modes—parallel load and hold—controlled by gated enable inputs (G1 and G2), allowing data entry at the D inputs to be latched on the positive clock transition when both enables are low, or maintaining the current state when high.

Features:-

• 3-State Outputs Interface Directly With System Bus
• Gated Output-Control LInes for Enabling or Disabling the Outputs
• Fully Independent Clock Virtually Eliminates Restrictions for Operating in One of Two Modes: – Parallel Load – Do Nothing (Hold)
• For applications such as Bus Buffer Registers
