ON Semiconductor 74LVX573MTC Octal Latch

The ON Semiconductor 74LVX573MTC is a high-performance CMOS octal latch that is part of the 74LVX family. This product is designed to interface directly with 3.3V systems, providing a robust solution for high-speed data storage and transfer applications. The 74LVX573MTC is particularly suitable for those applications that require a high-speed, low-power octal latch with a transparent data input mechanism.

This device features eight latches with three-state outputs for bus-oriented applications. Each latch is D-type and has a separate D-input and Q-output. The 74LVX573MTC is activated when the Latch Enable (LE) input is HIGH, allowing data on the D inputs to be stored in the latches. The data is retained as long as the LE is maintained in a HIGH state. When the LE input goes LOW, the latches retain the information stored regardless of changes at the D inputs.

The 74LVX573MTC also features an Output Enable (OE) input, which, when LOW, places the eight outputs in a normal operating mode. Conversely, when OE is HIGH, the outputs are in a high-impedance state, effectively isolating the latches from the bus. This high-impedance state not only conserves power but also prevents bus contention in a shared bus configuration.

Manufactured with ON Semiconductor's advanced sub-micron silicon gate CMOS technology, the 74LVX573MTC provides a low-voltage operation of 2.7V to 3.6V, which reduces power consumption and allows for a more reliable operation in mixed 3.3V/5V systems. The device is offered in a TSSOP-20 package, ensuring a compact footprint for space-constrained applications.

Key features of the 74LVX573MTC include:

• High-speed CMOS technology
• Octal D-type latches with three-state outputs
• Low-voltage operation (2.7V to 3.6V)
• Bus hold on data inputs eliminates the need for external pull-up resistors
• Latch Enable (LE) and Output Enable (OE) control inputs
• Low quiescent current consumption
• Support for live insertion and withdrawal (partial power-down)
• Industry-standard TSSOP-20 packaging

The 74LVX573MTC is an ideal choice for a wide range of applications, including memory address latching, data storage, and other situations where a temporary data storage is required. Its low power consumption and high-speed operation make it an excellent choice for modern electronic systems.
