Product Overview: 74HCT573 Octal D-type Transparent Latch
The 74HCT573 is a high-speed Si-gate CMOS device from NXP Semiconductors that belongs to the 74HCT family. This integrated circuit is designed to provide an octal D-type transparent latch with 3-state outputs. It is particularly well-suited for use in systems that require the capture and storage of eight bits of data in a transparent manner, with the ability to control the visibility of the output.
Key Features:
- Transparent Latch: The 74HCT573 allows data at its inputs to be outputted when the latch enable (LE) input is high, and latches the input data when LE is taken low.
- 3-State Outputs: The outputs can be placed in a high-impedance state, effectively removing the device from the bus or allowing for multiple devices to be connected to a common bus without interference.
- Compatibility: The device is TTL input compatible, allowing it to be used in mixed-technology environments and interface with both CMOS and TTL logic levels.
- High-Speed Performance: The 74HCT573 operates at a high-speed, with typical propagation delays comparable to the original 74LS series, but with the lower power consumption characteristic of CMOS technology.
- Wide Operating Voltage: It can operate with a supply voltage ranging from 4.5V to 5.5V, making it versatile for various applications.
Applications:
The 74HCT573 is used in a wide range of applications, including:
- Buffering and storage of data
- Address latching in memory devices
- System control and communication buses
- Interface between mismatched data buses
