DESCRIPTION
The 74LCX240 is a low voltage CMOS OCTAL BUS BUFFER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and high speed 3.3V applications; it can be interfaced to 5V signal environment for both inputs and outputs. It has same speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption.
■ 5V TOLERANT INPUTS AND OUTPUTS
■ HIGH SPEED: tPD= 6.5 ns (MAX.) at VCC= 3V
■ POWER DOWN PROTECTION ON INPUTS AND OUTPUTS
■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL= 24mA (MIN) at VCC= 3V
■ PCI BUS LEVELS GUARANTEED AT 24 mA
■ BALANCED PROPAGATION DELAYS: tPLH ≅tPHL
■ OPERATING VOLTAGE RANGE: VCC(OPR) = 2.0V to 3.6V (1.5V Data Retention)
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 240
■ LATCH-UP PERFORMANCE EXCEEDS 500mA (JESD 17)
■ ESD PERFORMANCE:
HBM > 2000V (MIL STD 883 method 3015);
MM > 200V
