SN74LS19A 的特性
- Functionally and Mechanically Identical to 'LS13, 'LS14, and 'LS132, Respectively
- Improved Line-Receiving Characteristics
- P-N-P Inputs Reduce System Loading
- Excellent Noise Immunity with Typical Hysteresis of 0.8 V
SN74LS19A 的说明
Each circuit functions as a NAND gate or inverter, but because of the Schmitt action, it has different input threshold levels for positive-going (VT+) and for negative-going (VT-) signals. The hysteresis or backlash, which is the difference between the two threshold levels (VT+ - VT-), is typically 800 millivolts.
These circuits are temperature-compensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals.
