DESCRIPTION
The 74VHC240 is an advanced high-speed CMOS OCTAL BUS BUFFER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

■ HIGH SPEED: tPD = 3.6ns (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 = 8 mA (MIN)
■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL
■ OPERATING VOLTAGE RANGE:
   VCC(OPR) = 2V to 5.5V
■ PIN AND FUNCTION COMPATIBLE WITH
   74 SERIES 240
■ IMPROVED LATCH-UP IMMUNITY
■ LOW NOISE: VOLP = 0.9V (MAX.)
