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
