The SN74AC563DW from Texas Instruments is a high-performance, octal D-type transparent latch with 3-state outputs designed to be used in a wide range of digital applications. This integrated circuit is part of the 74AC series and is commonly used for temporary data storage and transferring data to a bus-oriented system.
Key Features:
- Logic Type: D-Type Transparent Latch
- Output Type: 3-State
- Number of Channels: 8
- Supply Voltage: 2V to 6V
- Operating Temperature: -40°C to 85°C
- Package / Case: SOIC-20
- Mounting Type: Surface Mount
The SN74AC563DW is equipped with eight latches with three-state outputs for bus-oriented applications. Each latch is transparent, meaning that when the latch-enable (LE) input is high, the Q outputs will follow the data (D) inputs. When LE is taken low, the Q outputs will be latched at the levels that were set up at the D inputs.
A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without need for interface or pull-up components.
OE does not affect the internal operations of the latch. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.
The SN74AC563DW is characterized for operation from -40°C to 85°C, ensuring reliable performance over a range of environmental conditions. Its wide operating voltage range and high-speed performance make it suitable for interfacing with high-speed microprocessors, and it is commonly used in systems where high data throughput is required.
With its robust design and advanced technology, the SN74AC563DW from Texas Instruments is an excellent choice for your digital storage and data transfer needs.
