Overview of Texas Instruments CD54HC573F

The Texas Instruments CD54HC573F is a high-performance, CMOS Octal Transparent Latch with three-state outputs designed for use in applications requiring storage and isolation of any 8-bit data. This integrated circuit is part of the HC family, which is known for its high speed and low power consumption compared to other logic families. The CD54HC573F is specifically designed to operate with a power supply range of 2V to 6V, making it versatile for various digital applications.

Key Features

• Logic Type: Octal Transparent Latch
• Output Type: 3-State
• Number of Bits per Element: 8
• Supply Voltage Range: 2V to 6V
• Operating Temperature: -55°C to 125°C
• Package / Case: CerDIP-20

Functionality

The CD54HC573F features eight latches with three-state outputs. When the Latch Enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs. A separate Output Enable (OE) input is provided for each latch. When OE is low, the outputs are in a normal state; when OE is high, the outputs are in a high impedance state. This feature allows for the outputs to be connected directly to a bus-organized system without the need for bus transceivers.

Applications

The CD54HC573F is ideal for a wide range of applications that require temporary data storage or output isolation, such as:

• Buffer/Storage Registers
• Input/Output Ports
• Bus-Oriented Systems
