STMicroelectronics 74AC573 - Octal Latch

The 74AC573 is an integrated circuit manufactured by STMicroelectronics, renowned for their expertise in semiconductor solutions. This particular chip belongs to the high-speed CMOS family and features an octal transparent latch with three-state outputs designed to be used in a wide array of high-performance memory and data buffering applications.

Key Features

• High-Speed Operation: The 74AC573 operates at high speeds with a typical clock frequency of 150 MHz, ensuring rapid data transfer and processing capabilities for demanding applications.
• Octal D-Type Latch: The device contains eight latches with three-state standard 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 set up at the D inputs.
• Three-State Outputs: The outputs can be set to either a logical level or to a high-impedance state, making it easy to interface with bus-oriented systems by effectively disconnecting the output from the rest of the circuit.
• Low Power Consumption: This IC benefits from CMOS technology which ensures low power dissipation, offering a typical power consumption of only 40 µA in the quiescent state.
• Wide Operating Voltage Range: The 74AC573 can operate with a supply voltage ranging from 2V to 6V, accommodating various logic level requirements and providing design flexibility.
