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

Description

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 Specifications: Parameter Value Category Integrated Circuits (ICs)/Logic/Flip Flops Manufacturer XBLW Package PDIP-16 Voltage – Supply 4.75V~5.25V Clock Frequency 50MHz Propagation Delay 30ns@5V,45pF Operating Temperature 0℃~+70℃ Current – Output High(IOH) 2.6mA Function Reset Series 74LS Series Type D-Type Current – Output Low(IOL) 24mA Number of Bits per Element 4 Number of Elements 1 Setup Time 17ns Hold Time 3ns Quiescent Current 24mA Output Type Tri-State Trigger Type Rising Edge Pin Configuration: Pin No Pin Name Description 1 M Active Low Output Enable Input 1 2 N Active Low Output Enable Input 2 3 1Q Output Pin 1Q 4 2Q Output Pin 2Q 5 3Q Output Pin 3Q 6 4Q Output Pin 4Q 7 Clock Clock Pulse Input 8 GND Ground Pin 9 G1 Active low Input Enable Pin 1 10 G2 Active low Input Enable Pin 2 11 4D Data Input 4D 12 3D Data Input 3D 13 2D Data Input 2D 14 1D Data Input 1D 15 Clear Master Reset Input 16 V CC Chip Supply Voltage Footprint: Applications: Bus Buffer Registers Cascading applications High logic level controller Datasheet: SN74LS173N
