CD4099BM

Latches Overview

The CD4099BM is a CMOS 8-bit addressable latch manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and features a propagation delay of 400 ns at 5 V, 150 ns at 10 V, and 100 ns at 15 V. The device draws a maximum static current of 100 uA and has a maximum power supply current of 80 nA. Output drive capabilities include a low-level output current of 32 mA and a high-level output current of -4.2 mA. It is housed in a 16-pin SOIC-Narrow package and functions as a non-inverting latch with one input line and eight output lines.

Latches Feature Summary

• Provides serial input and parallel output storage functionality for data retention
• Supports 1-of-8 demultiplexer operation when specific control inputs are configured
• Allows continuous reading of all outputs independent of write disable or address states

Latches Applications

• Multi-line decoder circuits
• Analog-to-digital converter interfaces
• Addressable data storage systems

Latches Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm exact packaging and environmental compliance specifications. Ensure the component matches the required logic family standards and operating temperature ranges defined in the datasheet before integration into the design.

Latches Selection Notes

Select this component for designs requiring an 8-bit addressable latch with CMOS compatibility. Consider the 16-pin SOIC package for surface mount applications. Evaluate the propagation delay characteristics against system timing requirements to ensure signal integrity across the specified voltage and temperature ranges.

Latches Part Context

This part belongs to the CD4099B series of 8-bit addressable latches from Texas Instruments.
