SN54-74LS13

The SN54-74LS13 is designed as one kind of schmitt triggers dual gate / HEX inverter device that belongs to the SN54-74 family. SN54-74LS13 is capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. Additionally, it has greater noise margin than conventional inverters. Also each SN54-74LS13 circuit contains a Schmitt trigger followed by a Darlington level shifter and a phase splitter driving a TTL totem pole output.

The DC characteristics over operating temperature range (unless otherwise specified) of the SN54-74LS13 can be summarized as:(1)Positive-Going Threshold Voltage: 1.5 to 2.0 V;(2)Negative-Going Threshold Voltage: 0.6 V to 1.1 V;(3)Hysteresis: 0.4 to 0.8 V;(4)Input Clamp Diode Voltage: 0.65 to 1.5 V;(5)Input Current at Positive-Going Threshold: -0.14 mA;(6)Input Current at Negative-Going Threshold: -0.18 mA;(7)Input LOW Current: 0.4 mA;(8)Short Circuit Current: 20 to 100 mA.
