The SN74ACT533N, manufactured by Texas Instruments, is an integrated circuit that belongs to the 74ACT family. This high-speed, octal D-type transparent latch is designed for 4.5-V to 5.5-V VCC operation. It is widely used in various digital applications where temporary data storage is required, making it an essential component in the design of microprocessor and microcomputer systems.

Key Features

• Logic Type: Octal D-Type Transparent Latch with 3-state outputs
• Bus Hold: Provided on data inputs to eliminate the need for external pullup/pulldown resistors
• Logic Level: TTL Compatible
• Package: 20-Pin Plastic DIP (N)
• Operating Temperature Range: -40°C to 85°C

The device features eight latches with three-state outputs for bus-oriented applications. The latches appear transparent to data (i.e., the outputs change as the data inputs change) when the latch-enable (LE) input is high. When LE is low, the data that meets the setup-time requirements is latched. Data appears on the output only when the output-enable (OE) is low. If OE is high, the output is in the high-impedance state, which is neither high nor low, allowing for the connection to a bus without affecting other devices connected to it.

Applications

The SN74ACT533N is versatile and can be used in a variety of applications. It is particularly useful in data storage, multiplexing, and as a buffer for bidirectional bus systems. Its robust design ensures reliable operation in extended industrial environments, making it suitable for:

• Memory storage and retrieval systems
• Computers and computer peripherals
• Data communication systems
• Instrumentation and control systems

With its high-performance and industry-standard DIP packaging, the SN74ACT533N is a reliable choice for designers and engineers looking for a latch that offers both functionality and durability. Texas Instruments' commitment to quality ensures that this component will perform to specifications in a wide range of operating conditions.
