CD4099BNSR

Latches Overview

The CD4099BNSR is a single-channel, 8-bit addressable latch manufactured by Texas Instruments. It belongs to the CD4000B CMOS logic series and features non-inverting outputs in a 16-pin SOIC package. The device operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55 °C to +125 °C. Key electrical parameters include a maximum static current of 100 µA and a maximum power supply current of 80 nA. Propagation delays vary with voltage: 400 ns at 5 V, 150 ns at 10 V, and 100 ns at 15 V. Output drive capabilities include a low-level output current of 32 mA and a high-level output current of -4.2 mA.

Latches Feature Summary

• Provides 8-bit data storage with individual bit addressing capability for precise control over stored states.
• Features non-inverting outputs that maintain logical consistency between input data and latched results.
• Utilizes CMOS technology to achieve low static power consumption suitable for battery-operated systems.

Latches Applications

• Data storage in digital control systems requiring parallel output access

Latches Procurement Notes

Verify the suffix NSR confirms the SOIC-16 surface-mount package and reel packaging format. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm the manufacturer is Texas Instruments to guarantee specified electrical characteristics and reliability standards are met.

Latches Selection Notes

Select this component when a single 8-bit latch with independent bit addressing is required in a surface-mount design. Compare propagation delay specifications against system clock speeds to ensure timing margins are sufficient. Verify that the 16-pin SOIC footprint aligns with the PCB layout constraints and thermal management requirements.

Latches Part Context

This part is part of the CD4000B series of CMOS logic devices, known for wide voltage operation and compatibility with standard TTL levels. The CD4099 specifically addresses the need for addressable latching within this family, offering a compact solution for managing multiple data lines without complex external decoding logic.

Latches Replacement Considerations

Check for CD4099BE for through-hole DIP-16 applications or CD4099BM96 for alternative SOIC variants. Verify pinout compatibility and electrical parameter equivalence before substitution.
