74LCX573BQX

The 74LCX573BQX is a high-performance D-Type Transparent Latch from ON Semiconductor. It features 8-bit data width with Tri-State outputs, making it suitable for bus-oriented applications. The latch has a propagation delay of 1.5 ns and operates over a supply voltage range of 2V to 3.6V, allowing compatibility with both 2.5V and 3.3V systems. Each latch is transparent when the latch enable (LE) is high, and the outputs reflect the data inputs. When LE is low, the outputs latch the data at the time of transition. The Tri-State outputs can be disabled via the output enable (OE) input, allowing multiple devices to share a common bus. The device is specified for operation from -40°C to +85°C, making it suitable for industrial environments. The 74LCX573BQX is offered in a compact 20-DQFN (2.5x4.5mm) package with an exposed pad for improved thermal performance. The surface mount package is ideal for space-constrained PCB designs. The latch is part of the 74LCX family, which provides low-voltage operation with high speed and low power consumption. Typical applications include memory address latching, data bus buffering, and general-purpose digital logic. The device is RoHS compliant.
