DM74LS14 Hex Inverter with Schmitt Trigger Inputs 74LS14 Hex Inverter with Schmitt Trigger Inputs General Description This device contains six independent gates each of which performs the logic INVERT function. Each input has hyster- esis which increases the noise immunity and transforms a slowly changing input signal to a fast changing, jitter free output. Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

Absolute Maximum Ratings(Note 1) Note 1: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Recommended Operating Conditions Note 2: VCC = 5V.

Electrical Characteristics

over recommended operating free air temperature range (unless otherwise noted) Note 3: All typicals are at VCC = 5V, TA = 25°C. Note 4: Not more than one output should be shorted at a time, and the duration should not exceed one second.
