This datasheet introduces the features and characteristics of SN5414, SN54LS14, SN7414, SN74LS14 HEX SCHMITT-TRIGGER INVERTERS.
The document describes the SN5414, SN54LS14, SN7414, and SN74LS14 devices as hex Schmitt-trigger inverters. These circuits function as inverters with different input threshold levels for positive-going (VT+) and negative-going (VT-) signals due to Schmitt action. They are temperature compensated and capable of being triggered from very slow input ramps while providing clean, jitter-free output signals.
| Supply Voltage (Voc) | 4.5 V to 5.5 V (SN5414/SN7414); 4.75 V to 5.25 V (LS series) |
|---|---|
| Operating Temperature Range | -55°C to +125°C (SN5414/SN7414); 0°C to +70°C (LS series) |
| High-Level Output Current | -0.8 mA (SN5414/SN7414); -0.4 mA (LS series) |
Yes, they are temperature compensated and can be triggered from the slowest of input ramps while giving clean output signals.
The recommended operating free-air temperature range is from -55°C to 125°C.
