CD4043BE

Latches Overview

The CD4043BE is a CMOS quad R-S latch featuring tri-state outputs, manufactured by Harris Corporation. It operates within a supply voltage range of 3V to 18V and supports a load capacitance of 50 pF. The device provides four independent logic circuits in a 16-pin DIP package. Key electrical characteristics include a propagation delay of 50ns and output currents of 6.8mA for both high and low states. It functions reliably across an industrial temperature range of -55°C to 125°C.

Latches Feature Summary

• Contains four independent R-S latch circuits with tri-state output capability
• CMOS technology ensures compatibility with standard logic families
• Supports wide operating voltage ranges for flexible system integration

Latches Applications

• Data storage and buffering in digital systems
• Interface control between microprocessors and peripheral devices
• State holding in sequential logic circuits

Latches Procurement Notes

Verify the manufacturer origin carefully, as the CD4043BE was originally designed by Harris Corporation but is now produced by various entities including Rochester Electronics and Texas Instruments. Confirm the specific datasheet version and pinout compatibility before integration. Ensure the component meets the required environmental specifications for your application, particularly regarding the operating temperature range and power supply requirements.

Latches Selection Notes

Select this component when a quad latch with tri-state outputs is required in a through-hole DIP package. Consider the 3V to 18V supply range and -55°C to 125°C temperature rating for harsh environments. Verify that the 50ns propagation delay and 6.8mA drive current meet the system timing and load requirements. Check for RoHS compliance status if environmental regulations apply to the final product.

Latches Part Context

The CD4043BE belongs to the 4000 series of CMOS logic devices, widely used in general-purpose digital applications. Originally developed by Harris Semiconductor, this part number represents a standard quad R-S latch. The device has been discontinued by the original manufacturer but remains available through authorized distributors and secondary market suppliers like Rochester Electronics.
