The IC component 74HC173D,653 is a 4-bit register with a parallel-load capability. It is a part of the 74HC series, which are high-speed CMOS logic ICs widely used in various electronic circuits. Here is an overview and key features of the 74HC173D,653:
1. Overview:
The 74HC173D,653 is a quad D-type flip-flop with 3-state outputs that can be used as a 4-bit register or as a 4-bit transparent latch. It has four independent data inputs (D0, D1, D2, and D3) and four parallel outputs (Q0, Q1, Q2, and Q3). The register can be loaded with new data while retaining the previous output states until a parallel load signal is received.
2. Key Features:
a. 3-state Outputs: The 74HC173D,653 offers 3-state outputs, which allow the output pins to be in three different states: high-level (logic 1), low-level (logic 0), or high impedance. This feature allows efficient sharing of bus systems and simplifies interfacing with other devices.
b. Parallel Load Capability: This component has a parallel-load capability, enabling multiple data inputs to be loaded simultaneously by strobing the parallel load signal. This feature provides flexibility in controlling and updating the register's contents.
