Product Overview: Texas Instruments 74HC373NSR

The Texas Instruments 74HC373NSR is a high-performance, octal transparent D-type latch with 3-state outputs from the 'HC373' family of logic devices. This integrated circuit is designed to offer a robust and reliable solution for temporary data storage and output buffering in a wide array of digital systems. The 74HC373NSR is particularly well-suited for implementing the interface and bus-holding functions in microprocessor and microcontroller-based applications.

Key Features

• Logic Type: Octal D-Type Transparent Latch
• Output Type: 3-State
• Number of Channels: 8
• Input Level: CMOS
• Output Level: CMOS
• Propagation Delay Time: 18ns at 4.5V, 15ns at 6V
• Operating Temperature: -40°C to +85°C
• Mounting Type: Surface Mount
• Package / Case: 20-SOIC

The device features 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 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 again.

Additionally, the 74HC373NSR has an output enable (OE) input that, when high, puts the I/O ports in a high-impedance state. This is particularly useful for sharing bus lines in a system and avoiding bus contention issues.

Manufactured with high-grade materials and adhering to strict Texas Instruments quality standards, the 74HC373NSR ensures excellent performance and durability. The device is available in a 20-SOIC package, which is ideal for compact PCB layouts and is compatible with automated surface-mount assembly processes.

In summary, the Texas Instruments 74HC373NSR is an essential component for designers looking for a reliable latch with the capability to interface directly with the high-speed switching found in modern digital systems. Its versatility and performance characteristics make it an excellent choice for a wide range of applications, from data storage to signal buffering and beyond.
