XC74UL14AA CMOS Logic ◆ CMOS Schmitt Trigger Inverter ◆ High Speed Operation tpd=4.35ns TYP ◆ Operating Voltage Range 2V~5.5V ◆ Low Power Consumption 1µA MAX ■ Applications ■ General Description ■ Features The XC74UL14AA is a CMOS Schmitt Trigger Inverter, manufactured using silicon gate CMOS fabrication. CMOS low power circuit operation makes high speed LS-TTL operations achieveable. With a wave forming buffer connected internally, stabilized output can be achieved as the circuit offers high noise immunity. As the XC74UL14AA is integrated into mini molded, SSOT-25 and SOT-25 packages, high density mounting is possible. High Speed Operation: tpd=4.35ns TYP Operating Voltage Range: 2V~5.5V Low Power Consumption: 1µA MAX Space Saving Package: SSOT-25 and SOT-25 ■ Pin Configuration ■ Function NC 1 A 2 GND 3 5 ● Palmtops ● Digital Equipment VCC INPUT OUTPUT A H L Y L H o H=High level, L=Low level 4 Y SSOT-25/SOT-25 (TOP VIEW) ■ Absolute Maximum Ratings Ta=-40˚C~85: PARAMETER SYMBOL RATINGS UNITS Power Supply Voltage VCC -0.5 ~ +6.0 V Input Voltage VIN -0.5 ~ +6.0 V Output Voltage VOUT -0.5 ~ VCC +0.5 V Input Diode Current IIK -20 mA Output Diode Current IOK ±20 mA Output Current IOUT ±25 mA VCC ,GND Current ICC, IGND ±50 mA Continuous Total Power Dissipation Pd 150 mW Storage Temperature Tstg Ordering Information XC74UL xxxxxx ab DESIGNATOR a DESCRIPTION Package Type N=SSOT-25 M=SOT-25 b Device Orientation R=Embossed Tape (Orientation of Device:Right) L=Embossed Tape -65 ~ +150 : (Orientation of Device:Left) Note: Voltage is all Ground standardized. 579 XC74UL14AA CMOS Logic ■ DC Electrical Characteristics PARAMETER SYMBOL VT + VCC(V) Ta=25: Ta=-40~85: MIN TYP MAX MIN MAX 3.0 - - 2.2 - 2.2 4.5 - - 3.15 - 3.15 5.5 - - 3.85 - 3.85 3.0 0.9 - - 0.9 - V T- 4.5 5.5 1.35 1.65 - - 1.35 1.65 - 3.0 0.25 - 1.2 0.25 1.2 VH 4.5 0.30 - 1.4 0.30 1.4 5.5 0.35 - 1.6 0.35 1.6 2.0 1.9 2.0 - 1.9 - 2.9 3.0 - 2.9 - 4.4 4.5 - 4.4 - - 2.48 - Threshold Voltage Hysteresis Voltage CONDITIONS 3.0 VOH Output Voltage 4.5 IOH=-50µA VIN=VIL 3.0 IOH=-4mA 2.58 - 4.5 2.0 IOH=-8mA 3.94 - - - 3.80 0.1 0.1 IOL=50µA - - 0.1 - - - 0.1 - 0.1 IOL=4mA - - 0.36 - 0.44 IOL=8mA -0.1 - 0.36 - 0.44 0.1 -1.0 1.0 - - 1.0 3.0 VOL 4.5 VIN=VIH 3.0 Input Current IIN 4.5 5.5 VIN=VCC or GND Quiescent Supply Current ICC 5.5 VIN=VCC or GND, IOUT=0µA - UNITS V V V 0.1 10.0 V µA ■ Switching Electrical Characteristics tr=tf=3ns o PARAMETER SYMBOL 15pF 3.3 - 2.8 12.8 1 15 5.0 - 2.1 8.6 1 10 50pF 3.3 - 4.3 16.3 1 18.5 ns 15pF 5.0 3.3 - 3.1 10.6 3.1 12.8 1 1 12 15 ns 5.0 - 2.5 8.6 1 10 50pF 3.3 - 4.4 16.3 1 18.5 ns - 5.0 5.0 - 3.4 10.6 2 10 10 - 1 - 12 10 - pF pF tPHL VIN=VCC or GND No Load, f=1MHz MIN TYP MAX MIN MAX ■ Recommended Operating Conditions PARAMETER SYMBOL VCC(V) CONDITIONS UNITS Supply Voltage Input Voltage VCC VIN - 2 ~ 5.5 0 ~ 5.5 V V Output Voltage VOUT - 0 ~ VCC V Operating Temperature Topr 3.0 4.5 -40 ~ +85 -4 -8 : 3.0 4 4.5 8 IOH Output Current IOL 580 UNITS VCC(V) Propagation Delay Time CIN Cpd Ta=-40~85: CL tPLH Input Capacitance Power Dissipation Capacitance CONDITIONS Ta=25: mA ns ■ Waveforms tr tf VCC 90% 90% Input 50% 50% 10% 10% GND PRR=1MHz duty cycle 50% tr=tf=3ns VOH 50% 50% Output VOL tPHL tPLH ■ Typical Application Circuit o VCC Pulse Input Output Generator ZOUT=50Ω CL Note: open output when measuring supply current 581
