Applications
The CD4044BE-NG is widely used in digital logic systems requiring reliable state storage, such as keyboard debouncing circuits, control panel latching, and bus arbitration logic. Its tri-state output capability makes it ideal for shared bus architectures in microcontroller peripherals and programmable logic controllers. The device also finds use in industrial control systems where multiple latch channels must be independently enabled or isolated from the data bus.

Frequently Asked Questions
What is the supply voltage range for the CD4044BE-NG?
The CD4044BE-NG operates over a wide supply voltage range of 3V to 18V, making it compatible with both 5V TTL logic systems and 12V or 15V CMOS environments commonly used in industrial applications.
How does the tri-state output work on the CD4044BE-NG?
The CD4044BE-NG features an active-high Output Enable (OE) pin that controls the tri-state outputs. When OE is low, all outputs are placed in a high-impedance state, effectively disconnecting them from the bus and allowing multiple devices to share the same output lines without conflict.
What are typical applications for the CD4044BE-NG?
Typical applications include data bus latching, keyboard debounce circuits, register storage in microprocessor systems, and control signal latching in industrial automation. The four independent S-R latches allow simultaneous management of multiple logic states in a single compact 16-PDIP package.
Is the CD4044BE-NG pin-compatible with other CD4000-series ICs?
Yes, the CD4044BE-NG follows the standard CD4000 CMOS logic family pinout conventions and is compatible with the CD4044B family across manufacturers. It can be used as a drop-in replacement in existing 16-PDIP footprints that conform to this standard pinout.
