DESCRIPTION
The 74VHC257 is an advanced high-speed CMOS QUAD 2-CHANNEL MULTIPLEXER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.
■ HIGH SPEED: tPD = 3.7ns (TYP.) at VCC = 5V
■ LOW POWER DISSIPATION: ICC = 4 μA (MAX.) at TA=25°C
■ HIGH NOISE IMMUNITY: VNIH = VNIL = 28 VCC (MIN.)
■ POWER DOWN PROTECTION ON INPUTS
■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 8mA (MIN)
■ BALANCED PROPAGATION DELAYS: tPLH ? tPHL
■ OPERATING VOLTAGE RANGE: VCC(OPR) = 2V to 5.5V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 257
■ IMPROVED LATCH-UP IMMUNITY
■ LOW NOISE: VOLP = 0.8V (MAX.)
