54LS365A DM54LS365A DM74LS365A Hex TRI-STATE Buffers June 1989 54LS365A DM54LS365A DM74LS365A Hex TRI-STATE Buffers General Description This device contains six independent gates each of which performs a non-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 common bus to opposite logic levels the disable time is shorter than the enable time of the outputs Features Y Alternate Military Aerospace device (54LS365A) is available Contact a National Semiconductor Sales Office Distributor for specifications Connection Diagram Dual-In-Line Package TL F 6427 – 1 Order Number 54LS365ADMQB 54LS365AFMQB 54LS365ALMQB DM54LS365AJ DM54LS365AW DM74LS265AM or DM74LS365AN See NS Package Number E20A J16A M16A N16E or W16A Function Table YeA Input G1 H X L L G2 X H L L A X X H L Output Y Hi-Z Hi-Z H L 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 6427 RRD-B30M1...
