ON Semiconductor MC14042BDG Overview

The ON Semiconductor MC14042BDG is a high-performance, quad D-type transparent latch designed for use in a wide range of digital applications. This integrated circuit (IC) is part of ON Semiconductor's extensive CMOS logic family and offers users a combination of low power consumption, high speed, and robust output drive capabilities.

Key Features

• Transparent Latches: Each of the four latches in the MC14042BDG is transparent, meaning that when the latch enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the last data presented at the inputs is latched and held at the outputs.
• 3-State Outputs: This device includes a 3-state output control pin (OC) for each latch, allowing for connection to common data buses or for output port expansion. When OC is high, the outputs are in a high impedance state, effectively isolating them from the bus.
• Wide Operating Voltage Range: The MC14042BDG operates over a wide voltage range from 3V to 18V, providing versatility in various application environments and compatibility with both TTL and CMOS logic levels.
• Low Power Consumption: The device is designed for low power operation, which makes it ideal for battery-powered and power-sensitive applications.
• High Noise Immunity: The inherent noise immunity of the CMOS technology used in the MC14042BDG ensures stable and reliable operation, even in electrically noisy environments.

Applications

The MC14042BDG is suitable for a broad range of applications, including but not limited to:

• Buffer/Storage Registers
