Product Overview: NXP 74HC573PW

The NXP 74HC573PW is a high-performance, octal D-type transparent latch that is a part of the 74HC family, which utilizes silicon-gate CMOS technology. This integrated circuit (IC) is designed to have the same high speed and low power consumption characteristics of LSTTL combined with the advantages of CMOS technology. The 74HC573PW is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

Key Features

• Logic Type: Octal D-type transparent latch
• Logic Family: 74HC
• Output Capability: Bus driver
• Package Type: TSSOP-20
• Supply Voltage Range: 2.0V to 6.0V
• Operating Temperature: -40°C to +125°C

Functional Description

The 74HC573PW features eight D-type latches with 3-state true outputs. The device is edge-triggered, capturing data on the rising edge of the clock signal. When the latch enable (LE) input is HIGH, the Q outputs follow the data (D) inputs. When LE is LOW, the latches store the information that was present at the D inputs a setup time preceding the HIGH-to-LOW transition of LE. The 3-state outputs are controlled by the output enable (OE) input. When OE is LOW, the outputs are active and reflect the data that is stored in the latches. Conversely, when OE is HIGH, the outputs are in a high-impedance state, allowing the outputs to interface directly with bus-oriented systems.

Applications

The NXP 74HC573PW is versatile and can be used in a wide array of applications, including:

• Buffer registers for data storage and transfer
• I/O ports in microprocessor and microcontroller systems
• Bidirectional bus drivers
• Working registers and temporary storage for digital data
