CD74HC533E: An Overview

The CD74HC533E is a high-speed CMOS logic octal transparent latch manufactured by Texas Instruments. It is designed to offer a robust buffering solution for systems that require the temporary storage of information. This component is part of the 74HC series, which is well-known for its high speed and low power consumption, making it a preferred choice for a wide range of digital applications.

The device features eight latches with three-state outputs, providing a convenient interface for bus-oriented systems. The transparent nature of the latches means that while the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs. This functionality is essential for systems that require data to be held stable while other operations are performed.

Another key feature of the CD74HC533E is its wide operating voltage range of 2V to 6V, which allows it to be used in various environments and interfaced with other logic families. The device's inputs are also characterized for operation from 5V down to Vcc (Voltage Common Collector).
