Product Overview: SN74ABT373N

The SN74ABT373N, manufactured by Texas Instruments, is an octal transparent D-type latch with 3-state outputs. This integrated circuit is designed to provide high-speed, low-power performance suitable for buffering data on the bus lines of the system. It features eight latches with three-state outputs for bus-oriented applications, making it an ideal choice for temporary storage of data, capturing the momentary state of a data line, and providing a controlled output stage.

Key Features

• Logic Type: D-Type Transparent Latch
• Number of Bits per Element: 8
• Output Type: 3-State
• Operating Voltage: 4.5V to 5.5V
• Output Current: ±24mA
• Propagation Delay Time: 3.8ns at 5V
• Operating Temperature: -40°C to +85°C
• Package / Case: 20-PDIP (0.300", 7.62mm)
• Mounting Type: Through Hole

The SN74ABT373N is characterized for operation from -40°C to +85°C, ensuring reliability across a wide range of environmental conditions. The device comes in a 20-pin PDIP (Plastic Dual-In-line Package) which is suitable for through-hole mounting techniques, providing ease of integration into a variety of electronic systems.

Functionality

Each latch of the SN74ABT373N can be transparently opened by holding the enable (OE) pin low, allowing data at the inputs to pass through to the outputs. When the OE pin is taken high, the latch output will be retained at its current state, effectively isolating the bus line. Additionally, the outputs can be placed in a high-impedance state, allowing for multiple devices to share a common bus line without interference.

Applications

The SN74ABT373N is versatile and can be utilized in a broad range of applications including:

• Temporary data storage
• Data multiplexing
• Memory address latching
• System control
• Bus transceiver with 3-state outputs

With its robust design and reliable performance, the SN74ABT373N from Texas Instruments stands out as a superior choice for designers seeking a high-quality octal transparent latch for their digital logic applications.
