| DM74LS153 Dual 4-Line to 1-Line Data Selectors/Multiplexers March 1998 DM74LS153 Dual 4-Line to 1-Line Data Selectors/Multiplexers General Description Each of these data selectors/multiplexers contains inverters and drivers to supply fully complementary, on-chip, binary decoding data selection to the AND-OR-invert gates. Separate strobe inputs are provided for each of the two four-line sections. n Performs at parallel-to-serial conversion n Strobe (enable) line provided for cascading (N lines to n lines) n High fan-out, low impedance, totem pole outputs n Typical average propagation delay times -- From data 14 ns -- From strobe 19 ns -- From select 22 ns n Typical power dissipation 31 mW Features n Permits multiplexing from N lines to 1 line Connection Diagram Dual-In-Line Package Logic Diagram DS006393-1 Order Number 54LS153DMQB, 54LS153FMQB, 54LS153LMQB, DM54LS153J, DM54LS153W, DM74LS153M or DM74LS153N See Package Number E20A, J16A, M16A, N16E or W16A DS006393-2 (c) 1998 Fairchild Semiconductor Corporation DS006393 www.fairchildsemi.com Function Table Select Inputs B X L L L L H H H H A X L L H H L L H H C0 X L H X X X X X X C1 X X X L H X X X X C2 X X X X X L H X X C3 X X X X X X X L H G H L L L L L L L L Y L L H L H L H L H Data Inputs Strobe Output Select inputs A and B are common to both sections.

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.
