DM54LS368A Datasheet | National Semiconductor

Description This device contains six independent gates each of which performs an inverting buffer function The outputs have the TRI-STATE feature When enabled the outputs exhibit the low impedance characteristics of a standard LS output with additional drive capability to permit the driving of bus lines without external resistors When disabled both the output transistors are turned off presenting a high-impedance state to the bus line Thus the output will act neither as a significant load nor as a driver To minimize the possibility that two outputs will attempt to take a mon bus to opposite logic levels the disable time is shorter than the enable time of the outputs Features Y Alternate Military Aerospace device (54LS368) is available Contact a National Semiconductor Sales Office Distributor for specifications Connection Diagram Dual-In-Line Package TL F 6430 - 1 Order Number 54LS368ADMQB 54LS368AFMQB 54LS368ALMQB DM54LS368AJ DM54LS368AW DM74LS368AM or DM74LS368AN See NS Package Number E20A J16A M16A N16E or W16A Function Table Ye A Inputs Output LL HL XH H L Hi-Z H e High Logic Level L e Low Logic Level X e Either Low or High Logic Level Hi-Z e TRI-STATE (Outputs are disabled) TRI-STATE is a registered trademark of National Semiconductor Corporation C1995 National Semiconductor Corporation TL F 6430 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 DM54LS and 54LS b55 C to a125 C DM74LS 0 C to a70 C Storage Temperature Range b65 C to a150 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...
