MC74HC259DT

Latches Overview

The MC74HC259DT is an 8-bit addressable latch fabricated using silicon gate CMOS technology. It operates within a voltage range of 2.0 V to 6.0 V and features non-inverting outputs. The device provides high noise immunity with input voltages tolerating up to 7 V, enabling interface between 5 V and 3 V systems. It includes power-down protection on inputs and outputs and offers ESD performance exceeding 2000 V via human body model testing.

Latches Feature Summary

• Provides 8-bit data storage with individual addressable latching capability
• Features high-speed operation comparable to equivalent Bipolar Schottky TTL devices while maintaining low CMOS power dissipation
• Includes power-down protection on both inputs and outputs to prevent undefined states during power transitions

Latches Applications

• Data storage in digital logic circuits
• Address decoding for memory or peripheral selection
• Interface bridging between 5 V and 3 V system domains

Latches Procurement Notes

Verify the specific suffix 'DT' corresponds to the TSSOP-16 package configuration required for your PCB layout. Confirm RoHS compliance status as manufacturing processes may vary by production batch. Check current lifecycle status, as older CMOS logic families may be subject to discontinuation notices. Ensure static-sensitive handling procedures are followed during assembly due to CMOS construction.

Latches Selection Notes

Select this component when an 8-bit latch with independent output control is required. It is suitable for designs needing compatibility with standard logic families. Consider the operating temperature range and supply voltage requirements against system constraints. Verify that the propagation delay characteristics meet the timing specifications of the target application circuit.
