MC44144P Description

Short technical summary and product information.

The MC44144P from Motorola Semiconductor is an integrated circuit designed for clock generation and frequency synthesis applications. This device operates within an input voltage range of 9V to 18V, with a specified startup voltage of 14.5V. It supports a maximum switching frequency of up to 250kHz and a duty cycle of 80%, making it suitable for various power management designs.

 

The MC44144P offers features such as frequency control and soft start, contributing to stable and efficient operation. It provides isolated output and includes fault protection mechanisms like current limiting, over-voltage protection, and short-circuit protection to ensure safe operation under various conditions. The component is housed in a 16-PDIP package designed for through-hole mounting, with dimensions of 0.300" (7.62mm) lead spacing.

 

This IC is specified for operation across a wide temperature range, from -25°C to 150°C (junction temperature). Its RoHS status is non-compliant, and it is classified under REACH as unaffected. The Moisture Sensitivity Level (MSL) is 1, indicating unlimited shelf life under recommended storage conditions.
