MC74HCT259ADTG

Latches Overview

The MC74HCT259ADTG is an 8-bit addressable latch from the HCT logic family, manufactured by onsemi. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 45 ns. The device is housed in a SOIC-16 surface-mount package and supports an operating temperature range from -55°C to +125°C. It draws a maximum working power supply current of 50 mA.

Latches Feature Summary

• Provides individual addressing for eight data outputs via dedicated address inputs.
• Maintains non-inverting output polarity relative to the selected address input.
• Ensures high noise immunity through HCT-compatible CMOS input thresholds.

Latches Applications

• Data storage in digital control systems
• Address decoding circuits
• Parallel data buffering

Latches Procurement Notes

Verify component authenticity against official datasheets due to potential counterfeits. Confirm RoHS compliance status and check for End-of-Life notices or obsolescence warnings before procurement. Ensure the SOIC-16 package dimensions match design constraints.

Latches Selection Notes

Select this component when 8-bit latching with individual addressability is required in 5V logic environments. Verify that the 45 ns propagation delay meets system timing requirements. Ensure the wide industrial temperature range suits the operational environment.

Latches Part Context

This part belongs to the MC74HCT259A series of addressable latches. It is designed for applications requiring multiple independent data storage elements controlled by a common clock and address lines. The HCT series ensures compatibility with TTL logic levels while utilizing CMOS technology.
