General Description

The SNx4HC251 is a data selector/multiplexer containing full binary decoding to select 1of-8 data sources and

Key Features

  • 3-state version of ’HC151.
  • Wide operating voltage range of 2 V to 6 V.
  • High-current 3-state outputs interface directly with system bus or can drive up to 15 LSTTL loads.
  • Low power consumption, 80-μA max ICC.
  • Typical tpd = 9 ns.
  • ±6-mA output drive at 5 V.
  • Low input current of 1 μA max.
  • Perform parallel-to-serial conversion.
  • Complementary outputs provide true and inverted data 2.
