DESCRIPTION
The 74AC240 is an advanced high-speed CMOS OCTAL BUS BUFFER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS tecnology.

■ HIGH SPEED: tPD = 4.2ns (TYP.) at VCC = 5V
■ LOW POWER DISSIPATION:
   ICC = 4µA(MAX.) at TA=25°C
■ HIGH NOISE IMMUNITY:
   VNIH = VNIL = 28 % VCC (MIN.)
■ 50Ω TRANSMISSION LINE DRIVING
   CAPABILITY
■ SYMMETRICAL OUTPUT IMPEDANCE:
   |IOH| = IOL = 24mA (MIN)
■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL
■ OPERATING VOLTAGE RANGE:
   VCC (OPR) = 2V to 6V
■ PIN AND FUNCTION COMPATIBLE WITH
   74 SERIES 240
■ IMPROVED LATCH-UP IMMUNITY
