XC74WL125ASR

CMOS Logic NCMOS Logic Dual Bus Buffer NOperating Voltage Range : 2V ~ 5.5V NHigh Speed Operations NMSOP-8B Package : tpd =3.8ns TYP NLow Power Consumption : 2µA (max) ■Applications GPalmtops GDigital Equipment ■Description XC74WL125ASR is Dual Bus Buffer 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. ■Features High Speed Operations : tpd = 3.8ns TYP (VCC=5V) Operating Voltage Range : 2V ~ 5.5V Low Power Consumption: 2µA (max) Small Package : MSOP-8B ■Pin Configuration G1 A1 ■Functions INPUT 8 7 6 5 VCC 1 2 3 4 MSOP8 （TOP VIEW） G2 Y1 G H L L A X H L OUTPUT Y Z H L Y2 GND A2 H = High Level L = Low Level X = Don’t care Z = High Impedance ■Absolute Maximum Ratings PARAMETER SYMBOL VCC VIN VOUT IIK IOK IOUT ICC, IGND Pd Tstg RATINGS −0.5∼+6.0 −0.5∼+6.0 Ta=−40℃∼85℃ UNITS Ｖ Ｖ Ｖ mA mA mA mA mW ℃ 13 Power Supply Voltage Input Voltage Output Voltage Input Diode Current Output Diode Current Switch Output Current VCC, GND Current Power Dissipation (Ta=25℃) Storage Temperature −0.5∼VCC＋0.5 −20 ±20 ±25 ±50 300 −65∼＋150 Note : Voltage is all Ground standardized. 920 XC74WL125ASR ■Recommended Operating Conditions PARAMETER Supply Voltage Input Voltage Output Voltage Operating Temperature Input Rise and Fall Time SYMBOL VCC VIN VOUT Topr tr, tf CONDITIONS 2∼5.5 0∼5.5 0∼VCC −40∼+85 0∼200（VCC=3.3V） 0∼100（VCC=5V） UNITS Ｖ Ｖ Ｖ ℃ ns ■DC Electrical Characteristics PARAMETER SYMBOL VCC （V） 2.0 VIH Input Voltage VIL 3.0 5.5 2.0 3.0 5.5 2.0 3.0 VOH 4.5 3.0 4.5 Output Voltage 2.0 3.0 VOL 4.5 3.0 4.5 3 State Off-Leak Current Input Current Quiscent Supply Current IOZ IIN ICC 5.0 0∼5.5 5.5 VIN=VIL IOL=4mA IOL=8mA VIN=VIL or VIH, Vout=VCC or GND VIN=VCC or GND VIN=VCC or GND IOL=50μA VIN=VIH IOH=−4mA IOH=−8mA IOH=−50μA CONDITIONS Ta=25℃ MIN 1.5 2.1 3.85 − − − 1.9 2.9 4.4 2.58 3.94 − − − − − −0.25 −0.1 − TYP − − − − − − 2.0 3.0 4.5 − − − − − − − − − − MAX − − − 0.5 0.9 1.65 − − − − − 0.1 0.1 0.1 0.36 0.36 0.25 0.1 2.0 Ta=−40∼85℃ MIN 1.5 2.1 3.85 − − − 1.9 2.9 4.4 2.48 3.80 − − − − − −2.5 −1.0 − MAX − − − 0.5 0.9 1.65 − − − − − 0.1 0.1 0.1 0.44 0.44 2.5 1.0 20.0 μA μA μA V V V V UNITS 13 921 XC74WL125ASR ■Switching Electrical Characteristics PARAMETER SYMBOL VCC （V） 3.3 tPLH 5.0 3.3 5.0 3.3 tPHL 5.0 3.3 5.0 3.3 tZL 5.0 3.3 5.0 3.3 tZH 5.0 3.3 5.0 tLZ Output Disable Time tHZ 3.3 5.0 3.3 5.0 3.3 5.0 tosHL Input Capacitance Output Capacitance Power Dissipation Capacitance CIN COUT Cpd 3.3 5.0 − − − CL=15pF CL=50pF CONDITIONS MIN CL=15pF − − − − − − − − − − − − − − − − − − − − − − − − − − − Ta=25℃ TYP 5.6 3.8 8.1 5.3 5.6 3.8 8.1 5.3 5.4 3.6 7.9 5.1 5.4 3.6 7.9 5.1 9.5 6.1 9.5 6.1 − − − − 4 6 14 MAX 8 5.5 11.5 7.5 8 5.5 11.5 7.5 8 5.1 11.5 7.1 8 5.1 11.5 7.1 13.2 8.8 13.2 8.8 1.5 1 1.5 1 10 − − Ta=−40∼85℃ MIN 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 − − − − − − − MAX 9.5 6.5 13 8.5 9.5 6.5 13 8.5 9.5 6 13 8 9.5 6 13 8 15 10 15 10 1.5 1 1.5 1 10 − − （tr=tf=3ns） UNITS ns ns Propagation Delay Time ns CL=50pF RL=1kΩ CL=15pF RL=1kΩ CL=50pF RL=1kΩ CL=15pF RL=1kΩ CL=50pF RL=1kΩ CL=50pF RL=1kΩ CL=50pF CL=50pF ns ns ns Output Enable Time ns ns ns ns tosLH Output Pin Skew （Note） ns CL=50pF ns pF pF pF Note: tosLH and tosHL are the guaranteed parameters. tosLH = | tPLHm - tPHLn | , tosHL = | tPHLm - tPHLn | ■Noise Characteristics 13 ( tr=tf=3ns ) Ta=25℃ SYMBOL VOLP VOLV VIHD VILD CONDITIONS UNITS V V V V PARAMETER Not functioning output maximum dynamic VOL Not functioning output minimum dynamic VOL Minimum dynamic VIH Maximum dynamic VIL CL 50pF 50pF 50pF 50pF VCC(V) 5.0 5.0 5.0 5.0 MIN − −0.8 − − TYP 0.3 −0.3 − − MAX 0.8 − 3.5 1.5 922 XC74WL125ASR ■Propagation Delay Time ITypical Application Circuit VCC VCC Pulse Generator ZOUT=50Ω INPUT OUTPUT G GND CL IWaveforms tr 90% 90% 50% 10% tf VCC PRR=1MHz duty cycle 50% tr=tf=3ns INPUT 10% 50% GND VOH tPLH tPHL OUTPUT 50% 50% VOL 13 923 XC74WL125ASR ■Output Enable Time, Output Disable Time ITypical Application Circuit VCC Pulse Generator ZOUT=50Ω INPUT VCC G VCC VOUT OUTPUT GND RL= 1kΩ CL VCC IWaveforms tf 90% tr 90% 50% 10% 10% VCC PRR=1MHz duty cycle 50% tr=tf=3ns INPUT 50% GND tHZ 90% tZH VOH OUTPUT （A=VCC） tZL 50% tLZ GND VCC 13 OUTPUT （A=GND） 50% 10% VOL 924
