DM74125 Datasheet | National Semiconductor

Description This device contains four 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 TTL output with additional drive capability at the high Logic level to permit the driving of bus lines without external pull-up 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 Alternate Military Aerospace device (54125) is available Contact a National Semiconductor Sales Office Distributor for specifications Connection Diagram Dual-In-Line Package TL F 6540 - 1 Order Number 54125DMQB 54125FMQB DM54125J DM54125W or DM74125N See NS Package Number J14A N14A or W14B Function Table Ye A Inputs A L H X C L L H Output Y L 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 TL F 6540 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 5 5V Operating Free Air Temperature Range b 55 C to a 125 C DM54 and 54 DM74 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...
