MC74VHC259DT

Latches Overview

The MC74VHC259DT is an 8-bit addressable latch and 1-of-8 decoder fabricated with silicon gate CMOS technology. It operates within a supply voltage range of 2.0 V to 5.5 V. The device features LSTTL-compatible inputs, allowing interface between 5 V circuits and 3 V systems. Propagation delay is typically 7.6 ns at 5 V. Quiescent supply current is maximized at 40 µA across the operating temperature range of -55°C to +125°C. It is housed in a TSSOP-16 package.

Latches Feature Summary

• Provides four operational modes: addressable latch, memory, demultiplexer, and reset.
• Input structure tolerates voltages up to 7 V regardless of supply voltage.
• CMOS-compatible outputs ensure high noise immunity and low power dissipation.

Latches Applications

• General purpose storage applications in digital systems
• Interface between 5 V circuits and 3 V circuits
• Addressable latch and 1-of-8 decoding functions

Latches Procurement Notes

Verify the specific suffix DT corresponds to the TSSOP-16 package configuration required for your design. Confirm that the lead-free status aligns with your assembly process specifications. Ensure the ordering part number matches the exact revision level documented in the manufacturer's official datasheet to guarantee functional compatibility.

Latches Selection Notes

Select this component when high-speed operation comparable to Bipolar Schottky TTL is needed alongside CMOS low power consumption. The wide input voltage tolerance makes it suitable for mixed-voltage logic interfacing. Consider the thermal resistance and junction temperature limits if operating near the maximum ambient temperature extremes defined in the recommended operating conditions.
