DESCRIPTION

The 74LVX244 is a low voltage CMOS OCTAL BUS BUFFER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power, battery operated and low noise 3.3V applications.

■ HIGH SPEED:

  tPD=4.5ns (TYP.) at VCC = 3.3V

■ 5V TOLERANT INPUTS

■ POWER-DOWN PROTECTION ON INPUTS

■ INPUT VOLTAGE LEVEL:

  VIL = 0.8V, VIH = 2V at VCC =3V

■ LOW POWER DISSIPATION:

  ICC = 4 µA (MAX.) at TA=25°C

■ LOW NOISE:

  VOLP = 0.5V (TYP.) at VCC =3.3V

■ SYMMETRICAL OUTPUT IMPEDANCE:

  |IOH| = IOL = 4 mA (MIN) at VCC =3V

■ BALANCED PROPAGATION DELAYS:

  tPLH ≅ tPHL

■ OPERATING VOLTAGE RANGE:

  VCC(OPR) = 2V to 3.6V (1.2V Data Retention)

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 244

■ IMPROVED LATCH-UP IMMUNITY
