HD74LS251P - 1 of 8 Data Selector/Multiplexer

Download the HD74LS251P datasheet PDF. This datasheet also covers the HD74LS251 variant, as both devices belong to the same 1 of 8 data selector/multiplexer family and are provided as variant models within a single manufacturer datasheet.

Features

  • a strobe-controlled 3-state output. The strobe must be at a low logic level to enable this device. The 3-state outputs permit a number of outputs to be connected to a common bus. When the strobe input is high, both outputs are in a high-impedance state in which both the upper and lower transistors of each totem-pole output are off, and the output neither drives nor loads the bus significantly. When the strobe is low, the outputs are activated and operate as standard TTL totem-pole outputs. To.

HD74LS251 1 of 8 Data Selector / Multiplexer (with strobe and three-state outputs) REJ03D0467–0300 Rev.3.00 Jul.15.2005 This data selector / multiplexer contains full on-chip binary decoding to select one-of-eight data sources and features a strobe-controlled 3-state output. The strobe must be at a low logic level to enable this device. The 3-state outputs permit a number of outputs to be connected to a common bus. When the strobe input is high, both outputs are in a high-impedance state in which both the upper and lower transistors of each totem-pole output are off, and the output neither drives nor loads the bus significantly. When the strobe is low, the outputs are activated and operate as standard TTL totem-pole outputs.
