M74HC251 8-Channel Multiplexer (3-State)

The M74HC251 is an high speed CMOS 8-CHANNEL MULTIPLEXER (3-STATE) fabricated with silicon gate C2MOS technology.

This Multiplexer features both true (Y) and complement (W) outputs as well as STROBE input. When the STROBE is high, both outputs are in the high impedance state. When enabled, address information on the data select inputs determines which data input is routed to Y and W.

All inputs are equipped with protection circuits against static discharge and transient excess voltage

技术特性

  • VNIH = VNIL = 28 % VCC (MIN.)
• SYMMETRICAL OUTPUT IMPEDANCE:
  • |IOH| = IOL = 4mA (MIN)
• BALANCED PROPAGATION DELAYS:
  • tPLH tPHL
• WIDE OPERATING VOLTAGE RANGE:
  • VCC (OPR) = 2V to 6V
• PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 251
