Part number : 7414, DM74LS14, SN74LS14, HD74LS14
Function : Hex Inverter with Schmitt Trigger Inputs
Package : ZIP 5 Pin Type
Manufacturer : Sanken
This device contains six independent gates each of which performs the logic INVERT function. Each input has hysteresis which increases the noise immunity and transforms a slowly changing input signal to a fast changing, jitter free output. Each circuit functions as an inverter, but because of the Schmitt action, it has different input threshold levels for positive-going (VT+) and negative-going (VT–) signals.
These circuits are temperature compensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals.
1. Operation From Very Slow Edges
2. Improved Line-Receiving Characteristics
3. High Noise Immunity
