Product Overview
The device is supplied in the D package, SOIC-14. The package size is 8.65 mm x 6 mm, and the body size is 8.65 mm x 3.9 mm. For the SN74HC14, the operating free-air temperature range is -40°C to 85°C. Absolute maximum ratings include -0.5 V to 7 V supply voltage, ±25 mA continuous output current, ±50 mA continuous current through VCC or GND, and 150°C maximum junction temperature.
Electrical data covers Schmitt thresholds, hysteresis, output levels, leakage, supply current, timing, capacitance, ESD, and thermal resistance. At 25°C, propagation delay from A to Y is 55 ns typical at 2 V, 12 ns typical at 4.5 V, and 11 ns typical at 6 V. These characteristics support logic inversion, slow-edge signal conditioning, digital input cleanup, and pulse shaping where Schmitt-trigger thresholds are required.
