MC74AC259MG

Latches Overview

The MC74AC259MG is an 8-bit addressable latch in a 16-lead SOEIAJ package. It operates on a 2.0V to 6.0V supply with outputs capable of sourcing and sinking 24mA. The device features active HIGH outputs, an active LOW Common Clear, and an active LOW Enable. Propagation delays range from 6.0ns to 13.5ns at 5.0V. It supports serial-to-parallel conversion, random data entry, and demultiplexing.

Latches Feature Summary

• Provides eight bits of storage with individual output access for each bit
• Functions as a one-of-eight decoder or demultiplexer with active HIGH outputs
• Includes an active LOW Common Clear for resetting all latches simultaneously
• Supports serial-to-parallel conversion and random addressable data entry

Latches Applications

• General purpose digital system storage applications
• Serial-to-parallel data conversion circuits
• Active HIGH demultiplexing or decoding tasks
• Expandable memory systems requiring addressable latching

Latches Procurement Notes

Verify the specific ordering suffix 'M' corresponds to the SOEIAJ-16 package configuration required for your design. Confirm that the component meets Pb-Free specifications if environmental compliance is mandatory for your assembly process. Ensure the selected variant matches the voltage and speed requirements of your target application before finalizing procurement.

Latches Selection Notes

Select this component when an 8-bit addressable latch with active HIGH outputs is required. It is suitable for designs needing simultaneous storage and decoding capabilities within a single integrated circuit. Consider the propagation delay characteristics relative to your system clock speeds. Verify compatibility with your logic family voltage levels, specifically the 2.0V to 6.0V operating range.

Latches Part Context

This part belongs to the MC74AC259 series of high-speed CMOS logic devices. It is functionally identical to the ALS259 but utilizes AC technology for improved performance. The device is designed for general-purpose storage and decoding in digital systems, offering a compact solution for addressable latch applications.

Latches Replacement Considerations

The MC74AC259 is functionally identical to the ALS259. Other variants in the same family include MC74AC259N (PDIP), MC74AC259D (SOIC), and MC74ACT259 (TTL-compatible inputs). Ensure pinout and electrical characteristics match your existing design constraints when substituting.
