MC14099BDWR2G

Latches Overview

The MC14099BDWR2G is an 8-bit addressable latch manufactured by onsemi in a 16-pin SOIC package. It features serial data input and parallel output, with data entry controlled via three address pins (A0, A1, A2) and a write disable signal. The device operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports an ambient temperature range from -55°C to +125°C. Key electrical characteristics include a propagation delay from data to output Q ranging from 50 ns to 400 ns depending on voltage, and output drive currents up to 8.8 mA sink and -8.8 mA source at 15 V.

Latches Feature Summary

• Provides eight individually addressable latches for serial-to-parallel data conversion
• Includes master reset capability to clear all latch states simultaneously
• Supports driving low-power TTL or Low-Power Schottky TTL loads

Latches Applications

• Serial-to-parallel data conversion systems
• Addressable memory storage circuits
• Digital logic control interfaces requiring multiple independent latches

Latches Procurement Notes

Verify the specific ordering suffix 'DW' corresponds to the SOIC-16 Wide Body tape and reel packaging configuration. Confirm that the component meets RoHS compliance standards as indicated by the Pb-Free designation. Ensure the procurement channel sources the correct manufacturer part number to avoid compatibility issues with existing designs.

Latches Selection Notes

Select this component when an application requires multiple independent latches accessible via a common serial data line. The addressable architecture reduces pin count compared to parallel latching solutions. Verify that the operating voltage and temperature ranges align with the system environment requirements before integration.

Latches Part Context

This device belongs to the MC14099B series of 8-bit addressable latches. It is pin-for-pin compatible with the CD4099B standard. The product family offers a solution for managing multiple data storage elements using minimal interface lines, suitable for general-purpose digital logic applications.

Latches Replacement Considerations

The CD4099B is a confirmed pin-for-pin compatible substitute. Verify functional equivalence and parameter limits against the original datasheet specifications before substitution.
