That figure is used for timing closure over temperature and supply. ## Military temperature range — not just a spec sheet number Rated from -55°C to 125°C, this part suits environments where commercial or industrial parts would fail. The 14-DIP package is socket-friendly for prototyping. ## Quiescent current and output drive Quiescent current is a maximum of 2 µA across the supply range — negligible for battery-backed or always-on circuits. Each output can source or sink 5.2 mA, which is enough to drive one or two standard CMOS loads or a low-power LED indicator, but not enough for a relay coil or a long cable without a buffer. The symmetrical drive (5.2 mA high, 5.2 mA low) keeps rise and fall times balanced, reducing radiated emissions in edge-rate-sensitive designs.","metaTitle":"CD74HC20E 74HC NAND Gate, 2 Circuit, 4-Input, 14-DIP","metaDescription":"CD74HC20E dual 4-input NAND gate in 14-DIP. 2V to 6V supply, 17ns prop delay at 6V/50pF, -55°C to 125°C range.

The SN74HC20N has a narrower temperature range (-40°C to 85°C) and a 19 ns propagation delay at 6 V/50 pF, versus the CD74HC20E's -55°C to 125°C range and 17 ns delay."},{"question":"What is the difference between CD74HC20E and 74HC20?","answer":"The CD74HC20E is a specific order code within the 74HC20 functional device type. The 'E' suffix indicates the 14-pin DIP package and the extended -55°C to 125°C temperature range. A generic '74HC20' refers to the dual 4-input NAND function; the exact temperature grade and package depend on the suffix."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74HC20E","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74HC20E when reusing this data.
