CD4538 Dual Precision Monostable Multivibrator IC DIP-16

Description

CD4538 Dual Precision Monostable Multivibrator IC DIP-16 The CD4538 Dual Precision Monostable Multivibrator IC DIP-16 is a dual precision monostable multivibrator IC housed in a DIP-16 package, designed for high-stability pulse generation in digital timing circuits. Each independent section is triggered by either a leading-edge (A) or trailing-edge (B) transition, providing a wide range of output pulse widths determined by external Rₑₓₜ and Cₑₓₜ components connected to pins 6, 7, 9, and 10. The device operates across a broad supply range from 3VDC to 18VDC and features an active-low reset (CD) to immediately terminate the output pulse. Complementary outputs at Q and Q̅ provide versatile logic interfacing, while the VDD and VSS pins at 16 and 8 ensure stable biasing. Its retriggerable capability and 100ns typical propagation delay at 15VDC make it ideal for industrial control systems and precision delay applications. Features Dual independent monostable Multivibrator in a single package. Retriggerable and non-retriggerable operation capability. Wide operating voltage range. High noise immunity (CMOS technology). Stable pulse width determined by external RC components. Separate trigger and reset inputs. Low power consumption. Buffered outputs for reliable digital interfacing. Compatible with CMOS and TTL logic levels.
