SN74LS373 Octal Transparent Latch from ON Semiconductor

The SN74LS373 is a high-performance octal transparent D-type latch designed to interface directly with the speed requirements of popular 8-bit microprocessors. Manufactured by ON Semiconductor, this integrated circuit is part of the 74LS family, known for its low-power Schottky technology.

Key Features

• Eight latches in a single package for optimal board space utilization.
• Transparent latching mechanism ensures that while the latch-enable (LE) input is high, the Q outputs will follow the data (D) inputs.
• Output control for bus-oriented applications, with a 3-state output configuration that allows for connection to system buses without the need for interface or pull-up components.
• Direct bus connection when high output enable (OE) is inactive.
• Low power consumption characteristic of the 74LS series, enhancing system power efficiency.
• Wide operating voltage range compatible with most microprocessor systems.

Typical Applications

The SN74LS373 is versatile and can be used in a variety of applications including:

• Temporary storage of data
• Buffering for data buses
• Address latching in microprocessor systems
• System interfacing
• Memory address registers

Product Specifications

The device is offered in a standard 20-pin DIP (Dual In-line Package) or SOIC (Small Outline Integrated Circuit) package, making it suitable for both through-hole and surface mount technology (SMT) board designs. It operates over a temperature range from 0°C to 70°C, ensuring reliability across diverse environmental conditions.

Quality and Reliability

ON Semiconductor is committed to the highest standards of quality and reliability, and the SN74LS373 is no exception. It undergoes rigorous testing and quality control processes to ensure it meets the stringent requirements of the electronics industry.
