The -40°C to 125°C temperature range covers industrial and automotive under-hood ambient conditions — the 125°C ceiling matches AEC-Q100 Grade 1 thermal stress, though this part carries no formal AEC-Q certification in the record. Quiescent current is 2 µA maximum, which keeps the gate's own draw negligible in battery-powered or always-on subsystems. The output sinks 7.8 mA at low level; the high-level output current is not specified, so the pull-up drive is limited — the part is best used driving CMOS inputs rather than heavy loads. ## Schmitt trigger input and propagation delay The Schmitt trigger input hysteresis — low threshold 1 V to 3 V, high threshold 1.5 V to 4.2 V — rejects noise on slow-rising or noisy input signals. This makes the SN74HCS20DR suitable for debouncing switch inputs or conditioning signals from sensors with long rise times. Maximum propagation delay is 19 ns at 6 V with a 50 pF load. In a 3.3 V system the delay will be longer — the HC family's delay increases as supply voltage drops — so budget margin when the gate sits in a timing-critical path. ## Package and mounting for PCB integration Supplied in a 14-SOIC package (0.154\" body width, 3.90 mm), the SN74HCS20DR uses the standard SOIC-14 footprint shared by many logic gates. The supplier device package is also 14-SOIC, so no footprint mismatch between the case and the recommended land pattern. Available in Tape & Reel or Cut Tape options, the part is compatible with automated pick-and-place assembly.","metaTitle":"SN74HCS20DR Texas Instruments 74HCS NAND Gate, 2V-6V","metaDescription":"Active production SN74HCS20DR dual 4-input NAND gate with Schmitt trigger inputs. 2 µA quiescent, -40°C to 125°C, 14-SOIC.
