The hysteresis cleans up slow edges, noisy clock lines, or switch-contact bounce before the logic stage sees it. ## Output drive and timing — the bipolar TTL reality The output drive is asymmetric: 400µA source, 8mA sink. The 22ns propagation delay at 5V with a 15pF load is fast enough for most 5V logic buses. ## Schmitt-trigger thresholds — the noise budget The input logic levels are 0.5V low and 1.9V high, with the Schmitt hysteresis between them. That 1.4V window rejects noise that would toggle a plain inverter.","metaTitle":"SN74LS14NSR 74LS Hex Inverter with Schmitt Trigger, 5V","metaDescription":"TI SN74LS14NSR 74LS hex inverter with Schmitt-trigger inputs, 4.75V-5.25V supply, 22ns prop delay, 8mA sink output.
