XC74WL157ASR ETR1322_001 CMOS Logic ■GENERAL DESCRIPTION XC74WL157ASR is 2-channel multiplexer manufactured using silicon gate CMOS processes. The small quiescent current, which is one of the features of the CMOS logic, gives way to high speed operations which enables LS-TTL. With wave forming buffers connected internally, stabilized output can be achieved as the series offers high noise immunity. As the series is integrated into a mini molded, MSOP-8B package, high density mounting is possible. ■APPLICATIONS ■FEATURES ●Palmtops High Speed Operations : tpd = 4.1ns(TYP.) (VCC=5V) Operating Voltage Range : 2V ~ 5.5V ●Digital equipment Low Power Consumption : 2μA (MAX.)@Ta=25℃ CMOS Logic 2-channel Multiplexer Small Package : MSOP-8B ■PIN CONFIGURATION ■FUNCTIONS ST H L L L L INPUT SELECT A X L L H H X L H X X OUTPUT B Y Y X X X L H L L H L H H H L H L H=High level L=Low level X=Don’t care 1/5 XC74WL157ASR ■ABSOLUTE MAXIMUM RATINGS PARAMETER Supply Voltage Input Voltage Output Voltage Input Diode Current Output Diode Current Switch Output Current VCC,GND Current Power Dissipation (Ta = 25℃) Storage Temperature Range Ta=-40℃~85℃ SYMBOL VCC VIN VOUT IIK IOK IOUT ICC,IGND Pd Tstg RATINGS -0.5~+6.0 -0.5~+6.0 -0.5~VCC+0.5 -20 ±20 ±25 ±50 300 -65~+150 UNITS V V V mA mA mA mA mW ℃ Note : Voltage is all ground standardized. ■RECOMMENDED OPERATING CONDITIONS PARAMETER SYMBOL CONDITIONS UNITS Supply Voltage VCC 2~5.5 V Input Voltage VIN 0~5.5 V Output Voltage VOUT 0~VCC V Operating Temperature Range Topr -40~+85 ℃ Input Rise and Fall Time tr, tf 0~200（VCC=3.3V） ns 0~100（VCC=5V） ■DC ELECTRICAL CHARACTERISTICS PARAMETER SYMBOL VIH Input Voltage VIL CONDITIONS VCC(V) MAX.
