2 / 8 page TLF6430 May 1989 54LS368ADM54LS368ADM74LS368A Hex TRI-STATE Inverting Buffers General 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 signifi- cant load nor as a driver To minimize the possibility that two outputs will attempt to take a common bus to opposite logic levels the disable time is shorter than the enable time of the outputs Features Y Alternate MilitaryAerospace device (54LS368) is avail- able Contact a National Semiconductor Sales Office Distributor for specifications Connection Diagram Dual-In-Line Package TLF6430 – 1 Order Number 54LS368ADMQB 54LS368AFMQB 54LS368ALMQB DM54LS368AJ DM54LS368AW DM74LS368AM or DM74LS368AN See NS Package Number E20A J16A M16A N16E or W16A Function Table Y e A Inputs Output AG Y LL H HL L X H 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 RRD-B30M105Printed in U S A |
