QUAD 2 CHANNEL MULTIPLEXER (3-STATE)

DESCRIPTION The M74HC257 is an high speed CMOS QUAD 2 CHANNEL MULTIPLEXER (3-STATE) fabricated with silicon gate C2MOS technology. ■ HIGH SPEED : tPD = 11 ns (TYP.) at VCC = 6V ■ LOW POWER DISSIPATION: ICC =4µA(MAX.) at TA=25°C ■ HIGH NOISE IMMUNITY: VNIH = VNIL = 28 VCC (MIN.) ■ SYMMETRICAL

Quad 2-input multiplexer; 3-state

QUAD 2-CHANEL MULTIPLEXER (3-STATE)

Quad. 2-to-1-line Data Selectors/Multiplexers(with noninverted 3-state outputs)

Description The large output drive capability coupled with the 3-state feature make this device ideal for interfacing with bus lines in a bus organized system. When the output control input line is taken high, the outputs of all four multiplexers are sent into a high impedance state. When the out
