The 74ABT543CMSAX is an integrated circuit (IC) component that belongs to the 74ABT logic family. The IC is widely used in various digital applications, providing high-speed and low-power solutions. It features an octal transparent latch with 3-state outputs, making it ideal for data storage and control signal transmission in microprocessor systems and other digital circuits. Below are some key features and functions of the 74ABT543CMSAX:
1. Octal transparent latch: The IC consists of eight individual transparent D-type latches, which can store data based on the state of the latch enable (LE) input. When LE is high, the inputs (D0-D7) are latched and stored in the respective flip-flops. Data is not transferred when LE is low.
2. 3-state outputs: Each latch output (Q0-Q7) of the IC has a complementary output, denoted as Q?. These outputs can be put in high impedance state (Z) by enabling the output enable (OE) input. The 3-state outputs facilitate data transmission by allowing multiple devices to share the same bus without interference.
3. Fast operation: The 74ABT543CMSAX is designed to provide high-speed performance. It can operate at a maximum frequency of up to 125 MHz, allowing for rapid data transfers in various digital systems.
4. Low power consumption: A significant advantage of the IC is its low power consumption
