Product Overview: ON Semiconductor MC74LCX573DTG

The ON Semiconductor MC74LCX573DTG is a high-performance, octal transparent latch with 3-state outputs designed to interface directly with 5V systems while maintaining the speed of CMOS technology. It is a part of the LCX family, which is characterized by low voltage operation and is optimized for low power consumption and high noise immunity.

Key Features

• Logic Type: CMOS Octal Transparent Latch
• Number of Circuits: Eight
• Output Type: 3-State
• Voltage - Supply: 2.3V to 3.6V
• Operating Temperature: -40°C to 85°C
• Package / Case: TSSOP-20
• Mounting Type: Surface Mount

The device features latch enable (LE) and output enable (OE) inputs. When LE is held high, the Q outputs will follow the data (D) inputs. When LE is taken low, the Q outputs will be latched at the levels set up at the D inputs. A high on OE causes the outputs to assume a high impedance OFF-state. Control inputs tolerate voltages up to 5V independent of the VCC range.

Performance Advantages

The MC74LCX573DTG is designed for low voltage operation with a 5V tolerant input, which allows for direct interfacing with 5V TTL logic without the need for additional level shifting. This makes it ideal for mixed voltage applications and systems undergoing a transition from 5V to 3.3V. It also offers a significant advantage in power reduction and speed performance over standard CMOS and LSTTL logic types.

ON Semiconductor's innovative design ensures that this latch device has a reduced propagation delay time, and the outputs can drive up to 24mA, allowing for direct driving of a small LED display. Furthermore, the device's I/Os are guaranteed to be high impedance from DC up to the maximum operating frequency, ensuring reliable operation in a wide range of applications.

Applications

The MC74LCX573DTG is suitable for a variety of applications that require high-speed data latching, such as:

• Memory address latching
• Interface translation
• Bus isolation
• Data buffering
• Industrial controls

With its robust design and high-speed operation, the MC74LCX573DTG from ON Semiconductor is a versatile component for any electronics project or commercial product requiring reliable data retention and interfacing capabilities.
