MC74VHCT259ADTR2

Latches Overview

The MC74VHCT259ADTR2 is an 8-bit addressable latch and 1-of-8 decoder fabricated with silicon gate CMOS technology. It features LSTTL-compatible inputs and provides full 5 V CMOS level output swings, enabling use as a level converter for interfacing 3.3 V to 5.0 V systems. The device operates within a DC supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55°C to +125°C. Propagation delays are specified at 6.0 ns typical at 5.0 V with a 15 pF load.

Latches Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the TSSOP-16 package configuration required for your design. Confirm that the component meets RoHS compliance standards if mandated by your project specifications. Ensure the datasheet revision aligns with the manufacturing batch received. Cross-reference the pinout diagram with your PCB layout to guarantee correct signal routing for address, data, and control lines.

Latches Selection Notes

Select this component when TTL-compatible input thresholds are necessary alongside CMOS low power dissipation. The VHCT series is appropriate for applications requiring robust noise immunity and stable outputs. Consider the propagation delay characteristics relative to your system clock speeds. Verify that the TSSOP-16 package dimensions fit within your available board space constraints.
