Functional Features

• Octal transparent D-type latch with 3-state outputs
• High-speed CMOS logic for efficient operation
• Can drive bus lines or buffer memory address registers
• No external resistors required due to equivalent 25-Ω series resistors on output ports
• Latch-up performance exceeds 250 mA per JESD 17 standard

Advantages and Disadvantages

Advantages: - High-speed operation - Suitable for driving bus lines and buffering memory address registers - Eliminates the need for external resistors - Reliable latch-up performance

Disadvantages: - Limited supply voltage range (2 V to 6 V) - Requires careful handling due to sensitivity to electrostatic discharge (ESD)

Working Principles

The SN74HC573APWRE4 operates as an octal transparent D-type latch with 3-state outputs. It allows data inputs to be latched and stored when the latch enable (LE) signal is active. The output enable (OE) signal controls whether the latch outputs are in a high-impedance state or actively driving the bus lines. The latch-up performance of the IC ensures reliable operation even under heavy loads.

Detailed Application Field Plans

The SN74HC573APWRE4 can be used in various applications, including but not limited to: - Data storage and retrieval systems - Memory address buffering - Bus line driving in microprocessors and microcontrollers - Industrial automation and control systems - Communication equipment
