DESCRIPTION

The 74LVQ157 is a low voltage CMOS QUAD 2-CHANNEL MULTIPLEXER 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 = 7 ns (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 OUTPUT DRIVE

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 157

■ IMPROVED LATCH-UP IMMUNITY
