Overview
TC74HC251AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC251AP, TC74HC251AF 8-Channel Multiplexer (3-state) The TC74HC251A is a high speed CMOS 8-CHANNEL MULTIPLEXER fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
One of eight date input signals (D0-D7) is selected by decoding of the address input (A, B, C).
The selected data appears on two outputs; non-inverting (Y) and inverting (W).
When the strobe input is held high, both outputs are in the high-impedance state.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features • High speed: tpd = 15 ns (typ.
) at VCC = 5 V • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C • High noise immunity: VNIH = VNIL = 28% VCC (min) • Output drive capability: 10 LSTTL loads • Symmetrical output impedance: |IOH| = IOL = 4 mA (min) • Balanced pro...
