74LS14 Datasheet | National Semiconductor

Description 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 Connection Diagram Dual-In-Line Package TL F 6353 - 1 Order Number 54LS14DMQB 54LS14FMQB 54LS14LMQB DM74LS14M or DM74LS14N See NS Package Number E20A J14A M14A N14A or W14B Function Table Ye A Input A L H H e High Logic Level L e Low Logic Level Output Y H L C1995 National Semiconductor Corporation TL F 6353 RRD-B30M105 Printed in U S A Absolute Maximum Ratings (Note) If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Supply Voltage 7V Input Voltage 7V Operating Free Air Temperature Range b 55 C to a 125 C 54LS DM74LS 0 C to a 70 C Storage Temperature Range b 65 C to a 150 C Note The ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed The device should not be operated at these limits The parametric values defined in the ‘‘Electrical Characteristics’’ table are not guaranteed at the absolute maximum ratings The ‘‘Remended Operating Conditions’’ table will define the conditions for actual device operation Remended Operating Conditions Symbol VCC VT a VTb HYS IOH IOL TA Parameter Min Supply Voltage Positive-Going Input Threshold Voltage (Note 1) Negative-Going Input Threshold Voltage (Note 1) Input Hysteresis (Note 1) High Level Output Current Low Level Output Current Free Air Operating Temperature b 55 54LS14 Nom 5 16 08 08 b0 4 DM74LS14 Max 55 20 11 Min 4 75 14 05 04 Nom 5 16 08 08 b0 4 Units Max 5 25 19 1 V V V V m A m A C 45 15 06 04 4 125 0 8 70 Electrical Characteristics over remended operating free air temperature range (unless otherwise noted) Symbol VI VOH Parameter Input Clamp Voltage High Level Output Voltage Low Level Output Voltage...
