CD4099BE

Latches Overview

The CD4099BE is an 8-bit addressable latch from the Texas Instruments 4000B series, housed in a 16-pin PDIP package. It operates on a single non-inverting input to control eight outputs. Electrical specifications include a supply voltage range of 3 V to 18 V and a maximum static current of 100 uA. Propagation delay varies with voltage: 400 ns at 5 V, 150 ns at 10 V, and 100 ns at 15 V. The device supports low-level output currents up to 32 mA and high-level output currents of -4.2 mA. It functions within a temperature range of -55 °C to +125 °C.

Latches Feature Summary

• Provides 8-bit data storage with individual addressability via a single input line.
• Operates as a non-inverting latch compatible with standard CMOS logic levels.
• Supports wide supply voltage operation suitable for various industrial environments.

Latches Applications

• Data storage in digital systems requiring parallel output retention.
• Address decoding circuits utilizing the latch's multiplexer-like behavior.
• Interface modules connecting microcontrollers to peripheral devices.

Latches Procurement Notes

Verify the specific suffix 'BE' confirms the PDIP-16 through-hole package variant. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation, as indicated by the detailed specification reference. Ensure the operating environment remains within the specified -55 °C to +125 °C thermal limits to maintain guaranteed electrical performance parameters.

Latches Selection Notes

Select this component when a robust, wide-voltage 8-bit latch is required for through-hole assembly. The 4000B series offers high noise immunity and low power consumption compared to older logic families. Consider the propagation delay characteristics relative to system clock speeds. Verify that the 32 mA sink capability meets the load requirements of the connected circuitry without exceeding absolute maximum ratings.

Latches Part Context

This part belongs to the Texas Instruments CD4000B family of CMOS logic integrated circuits. The CD4099 specifically addresses the need for addressable latching in complex digital designs. It serves as a fundamental building block for memory interfaces and control logic within broader electronic systems designed for industrial or commercial applications.

Latches Replacement Considerations

The CD4099BNSR is a surface-mount alternative offering identical logical functionality in an SOIC-16 package. Other 4000-series latches may provide different pinouts or electrical characteristics; verify compatibility before substitution.
