The SN74LVC373AN is a high-performance, octal transparent D-type latch designed and manufactured by Texas Instruments. This integrated circuit is part of the LVC family, which is known for low-voltage operation and significant performance enhancements in systems. The device is optimized for 3.3V power supply but can operate with a supply voltage ranging from 2.7V to 3.6V, making it suitable for interfacing with 3.3V logic in mixed 3.3V/5V systems.

Key Features:

• Logic Type: Octal D-Type Latch with 3-State Outputs
• Operating Voltage: 2.7V to 3.6V, compatible with 5V systems
• Logic Family: LVC - Low-Voltage CMOS
• Output Capability: Bus Driver/Receiver
• Package: 20-Pin PDIP (Plastic Dual-In-Line Package)
• Data Flow Control: Transparent Latches with Latch Enable (LE) and Output Enable (OE) controls
• Propagation Delay: Fast propagation delay times
• Drive Strength: High-drive outputs (-24 mA IOH, 24 mA IOL)

Product Description:

The SN74LVC373AN features eight D-type latches with 3-state outputs designed to drive bus lines or buffer memory address registers. The device has a wide data bandwidth and is capable of supporting high-speed data transfer. The transparent nature of the latches means that while the latch enable (LE) input is high, the Q outputs will follow the data (D) inputs. When LE is taken low, the data that was present at the D inputs at the time the transition occurred is retained at the Q outputs until LE is returned high.

Additionally, the 3-state outputs can be placed in a high-impedance state, effectively disconnecting them from the bus, which is a necessary feature for bidirectional bus systems. The OE (Output Enable) input controls this feature.

The SN74LVC373AN is characterized for operation from -40°C to 85°C, making it reliable for industrial temperature ranges. Its robust construction ensures that it is resistant to latch-up and has the ability to withstand high electrostatic discharge (ESD) events.

With its combination of low-voltage operation, high-speed data handling, and robust physical construction, the SN74LVC373AN from Texas Instruments is an excellent choice for a wide range of applications, including computing, telecommunications, and consumer electronics, where reliable data storage and bus management are required.
