DESCRIPTION

The LVQ245 is a low voltage CMOS OCTAL BUS TRANSCEIVER (3-STATE) 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.

It has better speed performance at 3.3V than 5V LSTTL family combined with the true CMOS low power consumption.

■ HIGH SPEED: tPD = 6 ns (TYP.) at VCC = 3.3V

■ COMPATIBLEWITH TTL OUTPUTS

■ LOW POWER DISSIPATION:

ICC =5 µA (MAX.) at TA = 25 °C

■ LOW NOISE: VOLP = 0.5V(TYP.) at VCC = 3.3V

■ 75Ω TRANSMISSIONLINE DRIVING 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 SERIES 245

■ IMPROVED LATCH-UP IMMUNITY
