DESCRIPTION

The 74LVQ138 is a low voltage CMOS 3 TO 8 LINE DECODER (INVERTING) 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 = 5.5ns (TYP.) at VCC = 3.3 V

■ COMPATIBLE WITH TTL OUTPUTS

■ LOW POWER DISSIPATION:

ICC = 4 µA (MAX.) at TA=25°C

■ LOW NOISE:

VOLP = 0.2V (TYP.) at VCC = 3.3V

■ 75Ω TRANSMISSION LINE DRIVING

CAPABILITY

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 12mA (MIN) at VCC = 3.0 V

■ PCI BUS LEVELS GUARANTEED AT 24 mA

■ 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 138

■ IMPROVED LATCH-UP IMMUNITY
