Active stock — what the lifecycle status means for your BOM
No last-time-buy window to track, no successor to qualify. For a legacy 5V logic design or a repair stockroom, that means you can order it as a line item without the obsolescence risk premium baked into the price.
Military temperature range — where this buffer lives
That puts it into avionics bay electronics, satellite telemetry buffers, downhole instrumentation, and any outdoor telecom or defence rack that sees -40°C nights and +85°C cabinet interiors.
Two inverting buffers, 3-state, hex pinout — the logic function
Two independent buffer elements inside the 16-pin DIP: one handles 2 bits, the other handles 4 bits (hex configuration). Both are inverting with 3-state outputs, so you can disable the bus drivers when another device needs the line. The 4mA output drive is typical for HCT — enough to drive a few LSTTL inputs or a short PCB trace, but not a cable or a high-capacitance bus without a line driver stage.
Through-hole DIP — the repair and breadboard form factor
16-pin DIP with 0.300-inch body width, through-hole mounting. This is the package you want when you are reworking a legacy board, building a prototype on perfboard, or stocking a spare that needs to survive a soldering iron swap without reflow. The 16-PDIP supplier package code matches the standard DIP-16 footprint. No moisture sensitivity level to track — store it in a bin, not a dry cabinet.
