The SN74HCT373PWT is a high-performance, octal transparent D-type latch designed by Texas Instruments that is ideal for a wide range of applications requiring the temporary storage of data. This integrated circuit is part of the HCT family, which ensures compatibility with both CMOS and TTL logic levels, providing designers with a versatile and reliable solution for their digital systems.

Key Features

• Logic Family: HCT Logic
• Latch Type: D-Type Transparent Latch
• Number of Channels: 8
• Output Type: Tri-State
• Package: TSSOP (Thin Shrink Small Outline Package)
• Operating Temperature: -40°C to +85°C
• Supply Voltage: 4.5V to 5.5V

With its eight D-type latches, the SN74HCT373PWT can capture and hold eight bits of data simultaneously. Each latch features a transparent mode, which allows data to flow directly through when the latch enable (LE) input is high. When LE is taken low, the data present at the inputs at that moment is latched and held stable at the outputs, regardless of subsequent changes to the input data.

The tri-state outputs of the SN74HCT373PWT provide a high-impedance state when the output enable (OE) input is high, allowing for the outputs to be disconnected from the bus lines, which is especially useful in bus-oriented systems. This feature enables multiple devices to share the same output lines without the risk of bus contention.

The SN74HCT373PWT operates over a broad supply voltage range from 4.5V to 5.5V, making it suitable for interfacing with 5V systems. It is also characterized for operation from -40°C to +85°C, ensuring reliable performance in a variety of environmental conditions.

Texas Instruments' commitment to quality and reliability is reflected in the SN74HCT373PWT, which is designed to meet or exceed the stringent standards required by industrial and commercial applications. Whether you are designing data storage, buffer memory, or bus interface circuits, this octal latch is an excellent choice for ensuring data integrity and smooth operation.
