SN54AHCT14, SN74AHCT14 HEX SCHMITT-TRIGGER INVERTERS are Hex Schmitt-Trigger Inverters produced by Linear Technology. These products have excellent performance and can meet TTL voltage compatible, 250 mA latch-up performance, 2000-V human-body model, 200-V machine model and 1000-V charged device model requirements.
The document describes the SN54AHCT14 and SN74AHCT14 devices, which contain six independent inverters with Schmitt action. These circuits function as independent inverters but feature different input threshold levels for positive-going and negative-going signals to prevent noise-induced switching.
The datasheet details absolute maximum ratings, recommended operating conditions (supply voltage 4.5V to 5.5V), and electrical characteristics including hysteresis voltage and propagation delay times. It also lists various package options such as PDIP, SOIC, SSOP, TSSOP, QFN, and CDIP with specific temperature ranges for military and commercial grades.
