ON Semiconductor MC74HC373ADT Octal D-Type Latch

The ON Semiconductor MC74HC373ADT is a high-performance, octal D-type latch that is part of the high-speed CMOS family. This integrated circuit is designed to provide the functionality of eight latches in a single package, making it an ideal choice for a wide range of applications in the industrial, automotive, and consumer electronics sectors. The device is optimized to operate with a power supply range of 2V to 6V, ensuring compatibility with both low-voltage and standard logic levels.

With its robust latch function, the MC74HC373ADT ensures data integrity by allowing information to be stored temporarily and accessed when required. Each latch has a 3-state output, which can be either high, low, or high-impedance. This feature provides the ability to interface directly with bus-oriented systems, where multiple devices can share the same data lines without interference.

Key Features:

• Logic Type: Octal D-Type Latch with 3-State Outputs
• Package / Case: TSSOP-20
• Operating Temperature: -55°C to +125°C
• Supply Voltage Range: 2V to 6V
• High-Speed Performance: Ensures swift data processing and transfer.
• Low Power Consumption: Ideal for battery-operated and power-sensitive applications.
• Output Drive Capability: Capable of driving 15 LSTTL loads.
• Pin and Function Compatibility: With standard 74LS373 latches.

The device's transparent latch enables data to flow from input to output when the latch-enable (LE) input is high, and latches the input data when LE is low. The octal format of the MC74HC373ADT provides a compact solution for systems requiring multiple latching mechanisms, without the need for multiple ICs, saving both space and cost.

Additionally, the MC74HC373ADT features a bus-hold circuitry which eliminates the need for external pull-up resistors, simplifying the design and reducing component count. The combination of high-speed operation, low power consumption, and 3-state outputs make the MC74HC373ADT from ON Semiconductor a versatile and efficient solution for a wide array of digital logic applications.
