Overview
DM54LS154 DM74LS154 4-Line to 16-Line Decoders Demultiplexers May 1989 DM54LS154 DM74LS154 4-Line to 16-Line Decoders Demultiplexers General Description Each of these 4-line-to-16-line decoders utilizes TTL circuitry to decode four binary-coded inputs into one of sixteen mutually exclusive outputs when both the strobe inputs G1 and G2 are low The demultiplexing function is performed by using the 4 input lines to address the output line passing data from one of the strobe inputs with the other strobe input low When either strobe input is high all outputs are high These demultiplexers are ideally suited for implementing high-performance memory decoders All inputs are buffered and input clamping diodes are provided to minimize transmission-line effects and thereby simplify system design Features Y Y Y Y Y Y Decodes 4 binary-coded inputs into one of 16 mutually exclusive outputs Performs the demultiplexing function by distributing data from one input line to any one of 16 outputs Input clamping diodes simplify system design High fan-out low-impedance totem-pole outputs Typical propagation delay 3 levels of logic 23 ns Strobe 19 ns Typical power dissipation 45 mW Connection and Logic Diagrams Dual-In-Line Package TL F 6394–1 Order Number DM54LS154J DM74LS154WM or DM74LS154N See NS Package Number J24A M24B or N24A TL F 6394 – 2 C1995 National Semiconductor Corporation TL F 6394 RRD-B30M105 Printed in U S A Absolute Maximum Ratings (Note) 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 ‘‘Recommended Operating Conditions’’ table will define the conditions for actual device operation If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability...
