DESCRIPTION

The 74LCX244 is a low voltage CMOS OCTAL BUS BUFFER (NON-INVERTED) 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.

■ 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 244
