Frequently Asked Questions
What is the maximum operating frequency of the CD4042BE?
The CD4042BE supports a maximum frequency of 8MHz at nominal supply voltage with a 50pF load capacitance. This makes it suitable for moderate-speed digital logic applications such as data latching, bus synchronization, and state machine designs operating within standard CMOS clock ranges.
What supply voltage range does the CD4042BE support?
The CD4042BE operates over a wide supply voltage range of 3V to 15V, which is typical of the 4000-series CMOS family. This broad range ensures compatibility with both 5V TTL-level systems and higher-voltage CMOS designs, making it highly versatile for various embedded and industrial applications.
What does the programmable trigger type feature mean on the CD4042BE?
The CD4042BE includes a POLARITY input pin that selects between positive-edge and negative-edge triggered latch behavior. When POLARITY is high, data is latched on the rising clock edge; when low, on the falling edge. This flexibility allows designers to synchronize with different clock polarities without adding external inverters.
What are common applications for the CD4042BE?
The CD4042BE is commonly used as a data register in microcontroller I/O expansion, parallel data bus latching, frequency divider control logic, and low-power state machines. Its quad-latch structure and programmable clocking make it ideal for consumer electronics, industrial control panels, and legacy CMOS digital circuit designs.
Is the CD4042BE RoHS compliant and what package does it come in?
Yes, the CD4042BE is Pb-free (RoHS compliant) as indicated by its Pbfree Code: Yes. It is housed in a standard 16-pin PDIP (Plastic Dual-In-Line Package), coded R-PDIP-T16 per JESD-30, which is widely available and easy to use in both through-hole prototyping and production PCB assemblies.
