MC14099BCP

Latches Overview

The MC14099B is an 8-bit addressable latch from the 4000 series, featuring serial data input and parallel output. It utilizes three address pins (A0, A2) to select specific latches for write operations when Write Disable is low. The device operates within a supply voltage range of 3.0 Vdc to 18 Vdc. Propagation delay from Data to Output Q ranges from 50 ns to 400 ns depending on voltage. It includes Master Reset capability and is capable of driving two Low-power TTL loads or one Low-power Schottky TTL load.

Latches Feature Summary

• Serial data input with parallel output across eight independent latches
• Address decoding via three pins for selective latch writing
• Master Reset functionality available for all latches
• Pin-for-pin compatible with CD4099B

Latches Applications

• Data storage in microprocessor systems
• Shift register applications
• Parallel-to-serial conversion circuits

Latches Procurement Notes

Verify package type availability as the SOIC-16 variant may be discontinued. Confirm if NLV prefix is required for automotive qualification. Check current ordering information for tape and reel specifications. Ensure compliance with RoHS standards. Validate pin assignment against schematic requirements before procurement.

Latches Selection Notes

Select this component for applications requiring addressable latching with serial input. Consider the 3V to 18V operating range for flexibility. Evaluate propagation delays against system timing constraints. Verify drive capabilities match downstream logic loads. Check for alternative packages if surface mount is not preferred.

Latches Part Context

Part of the 4000 series CMOS logic family. Designed for general-purpose digital logic applications. Offers high noise immunity and low power consumption typical of CMOS technology. Compatible with standard TTL logic levels under specified conditions.

Latches Replacement Considerations

CD4099B is a direct pin-for-pin replacement. Verify electrical characteristics match application requirements. Check package compatibility if substituting physical form factors.
