It gives you a small, fast scratchpad for temporary data holding, status flags, or configuration nibbles in a through-hole design. ## Temperature range — the full military span If your board lives in an engine bay, a satellite orbit, or a downhole tool, the CD74HC670E keeps its register contents valid across the extremes without needing a screened or ceramic-package variant. ## Package and mounting — through-hole for retrofit and prototyping Housed in a 16-pin PDIP (0.300\" body width, 7.62mm row spacing), this is a through-hole part. That matters if you are replacing a failed register in legacy equipment, breadboarding a logic circuit, or building a one-off where SMT reflow is impractical. The 16-DIP footprint is standard — no surprises on the layout side.","metaTitle":"CD74HC670E 74HC Register File, 4x4 Tri-State, -55 to 125°C","metaDescription":"CD74HC670E 74HC 4x4 register file with tri-state outputs. 2V-6V supply, -55°C to 125°C range, 16-DIP.
