ON Semiconductor 74LVX373MTC Octal Transparent Latch

The 74LVX373MTC from ON Semiconductor is a high-performance CMOS octal transparent latch designed for use in applications requiring high-speed and low-power consumption. This integrated circuit is a part of the 74LVX family, which operates at a lower voltage range of 2.7V to 3.6V, making it ideal for battery-operated and portable devices where power efficiency is crucial.

Featuring eight latches with three-state outputs, the 74LVX373MTC allows for the storage of eight bits of data. Each latch is transparent, meaning that when the latch enable (LE) input is high, the Q outputs will follow the data (D) inputs. As soon as the LE input goes low, the data that was present at the D inputs at the time the transition occurred will be retained at the Q outputs until the LE is enabled once again.

The device also includes an output enable (OE) feature, which, when low, allows the data to be accessed from the outputs. When OE is high, the outputs are in a high impedance state, which is particularly useful for interfacing with bus-oriented systems where multiple devices may need to share the same data lines.

The 74LVX373MTC is housed in a compact 20-pin TSSOP (Thin Shrink Small Outline Package) that offers a space-saving solution for PCB design. Its pin configuration is carefully designed to allow for convenient placement and routing in complex circuits.

Key features of the 74LVX373MTC include:

• Low voltage operation: 2.7V to 3.6V
• High-speed performance: tPD 4.5 ns (max) @ 3.3V
• Power-down high impedance inputs and outputs
• Supports live insertion and withdrawal (partial power-down)
• ±24 mA output drive at 3.3V
• Bus hold on data inputs eliminates the need for external pull-up resistors
• Lead-free and RoHS compliant

This product is suitable for a wide range of applications, such as memory address latching, data storage, multiplexing, and as a buffer for bus-oriented systems. The ON Semiconductor 74LVX373MTC offers a reliable and efficient solution for designers looking to optimize their digital systems with a latch that combines low-voltage operation with high-speed capabilities.
