DESCRIPTION
The LVQ244 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 low noise 3.3V applications.
■ HIGH SPEED: tPD = 6 ns (TYP.)at VCC = 3.3V
■ COMPATIBLEWITH TTL OUTPUT
■ LOW POWER DISSIPATION: ICC =4 µA (MAX.) at TA = 25 oC
■ LOW NOISE: VOLP = 0.4V (TYP.) at VCC = 3.3V
■ 75Ω TRANSMISSIONLINE OUTPUT DRIVE CAPABILITY
■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 12 mA (MIN)
■ PCI BUS LEVELSGUARANTEED AT 24mA
■ BALANCEDPROPAGATIONDELAYS: tPLH ≅ tPHL
■ OPERATING VOLTAGERANGE: VCC (OPR)= 2V to 3.6V (1.2VData Retention)
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES244
■ IMPROVED LATCH-UP IMMUNITY
