MC74AC259DG

Latches Overview

The MC74AC259DG is an 8-bit addressable latch from the AC logic series, housed in a 16-lead SOIC package. It operates on a supply voltage of 2.0 V to 6.0 V. Propagation delays range from 1.5 ns to 17.5 ns depending on the signal path and voltage. The device features active HIGH outputs with sink/source currents up to 24 mA. It includes an active LOW Master Reset and Enable inputs.

Latches Feature Summary

• Provides eight bits of storage with individual output access for each bit
• Supports serial-to-parallel conversion and random addressable data entry
• Functions as an active HIGH demultiplexer or decoder when configured appropriately
• Includes a common clear function to reset all latches simultaneously

Latches Applications

• General purpose digital system storage applications
• Serial-to-parallel data conversion circuits
• Active HIGH demultiplexing or decoding tasks

Latches Procurement Notes

Verify the specific ordering suffix 'D' corresponds to the SOIC-16 package configuration required for your design. Confirm that the lead-free status aligns with your assembly process requirements. Ensure the operating temperature range meets your environmental specifications before finalizing procurement.

Latches Selection Notes

Select this component when an 8-bit addressable latch with high-speed performance is needed. The AC series offers faster switching than standard HC devices while maintaining CMOS compatibility. Consider the 2.0 V to 6.0 V supply range for flexibility in various digital logic environments.

Latches Part Context

This part belongs to the MC74AC259 family of addressable latches. It is functionally identical to the ALS259 but utilizes advanced CMOS technology for higher speed and lower power consumption. The device is designed for general-purpose storage and decoding in digital systems.

Latches Replacement Considerations

The MC74ACT259 is a compatible variant within the same family offering TTL-compatible input thresholds. Verify pinout and electrical characteristics match your application requirements when substituting.
