TECHNICAL DATA KK74LV244 OCTAL BUFFER/LINE DRIVE; 3-STATE The KK74LV244 is a low-voltage Si-gate CMOS device and is pin and function compatible with KK74HC/HCT244. The KK74LV244 is an octal non-inverting buffer/line driver with 3-state outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on nOE causes the outputs to assume a high impedance OFF-state. The KK74LV244 is identical to the KK74LV240 but has non-inverting outputs. • • • • • N SUFFIX PLASTIC DIP 20 1 DW SUFFIX SO 20 1 Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 1.2 to 3.6 V Low Input Current: 1.0 µA, 0.1 µА at Т = 25 °С Output Current: 8 mA at VCC = 3.0 V High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION KK74LV24 Plastic DIP KK74LV244D SOIC TA = -40° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT 1A0 1Y0 16 1Y1 6 14 1Y2 8 12 1Y3 11 9 2Y0 13 7 2Y1 2A0 15 5 2Y0 2A1 17 3 2Y1 1A2 1A3 2A0 2A1 OUTPUT ENABLES 18 4 1A1 DATA INPUTS 2 1OE 2OE 1OE 1 20 VCC 1A0 2 19 2OE 2Y3 3 18 1Y0 1A1 4 17 2A3 2Y2 5 16 1Y1 1A2 6 15 2A2 2Y1 7 14 1Y2 1A3 8 13 2A1 2Y0 9 12 1Y3 10 11 2A0 NONINVERTING OUTPUTS GND FUNCTION TABLE 1 19 Input PIN 20=VCC PIN 10 = GND Output nOE nAn nYn L L L L H H H X Z H= high level L = low level X = don’t care Z = high impedance 1 KK74LV244 MAXIMUM RATINGS* Symbol Value Unit -0.5 to +5.0 V DC Input diode current ±20 mA DC Output diode current ±50 mA DC Output source or sink current ±35 mA ICC DC VCC current ±70 mA IGND DC GND current ±70 mA VCC IIK * 1 IOK *2 IO * 3 PD Tstg TL Parameter DC supply voltage Power dissipation per package: * Plastic DIP SO 4 mW 750 500 Storage Temperature -65 to +150 °C 260 °C Lead Temperature, 1.5 mm (Plastic DIP Package), 0.3 mm (SO Package) from Case for 4 Seconds * Maximum Ratings are those values beyond which damage to the device may occur.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open. 2 KK74LV244 DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) Symbol Parameter Test VCC conditions V Guaranteed Limit 25°C -40°C to 85°C Unit 125°C min max min max min max VIH HIGH level input voltage 1.2 2.0 3.0 3.6 0.9 1.4 2.1 2.5 - 0.9 1.4 2.1 2.5 - 0.9 1.4 2.1 2.5 - V VIL LOW level input voltage 1.2 2.0 3.0 3.6 - 0.3 0.6 0.9 1.1 - 0.3 0.6 0.9 1.1 - 0.3 0.6 0.9 1.1 V VOH HIGH level output voltage VI = VIH or VIL IO = -50 µА 1.2 2.0 3.0 3.6 1.1 1.92 2.92 3.52 - 1.0 1.9 2.9 3.5 - 1.0 1.9 2.9 3.5 - V VI = VIH or VIL IO = -8 mА 3.0 2.48 - 2.34 - 2.20 - V VI = VIH or VIL IO = 50 µА 1.2 2.0 3.0 3.6 - 0.09 0.09 0.09 0.09 - 0.1 0.1 0.1 0.1 - 0.1 0.1 0.1 0.1 V VI = VIH or VIL IO = 8 mА 3.0 - 0.33 - 0.4 - 0.5 V VI = VCC or 0 V * - ±0.1 - ±1.0 - ±1.0 µА 1.2 * - ±0.5 - ±5 - ±10 µА * - 8.0 - 80 - 160 µА VOL II LOW level output voltage Input current IOZ Three state leakage 3-state outputs current VI (01,19) = VIH VO =VCC or 0 V ICC Supply current VI =VCC or 0 V IO = 0 µА * VCC = 3.3 ± 0.3 V 3 KK74LV244 AC ELECTRICAL CHARACTERISTICS (CL=50 pF, tr=tf=6.0 ns) Symbol Parameter Test VCC conditions V Guaranteed Limit 25°C -40°C to 85°C min max min Unit 125°C max min max tPHL, tPLH Propagation delay , 1An to VI = 0 V or VCC 1Yn, 2An to 2Yn Figure 1 and 3 1.2 2.0 * - 100 24 15 - 125 30 19 - 150 36 23 ns tPHZ tPLZ Propagation delay, 1OE to VI = 0 V or VCC 1Yn, 2OE to 2Yn Figure 2 and 4 1.2 2.0 * - 140 30 20 - 175 35 24 - 210 41 28 ns tPZH tPZL Propagation delay, 1OE to VI = 0 V or VCC 1Yn, 2OE to 2Yn Figure 2 and 4 1.2 2.0 * - 140 32 20 - 175 40 25 - 210 48 30 ns tTHL, tTLH Output Transition Time, Any Output 1.2 2.0 * - 60 16 10 - 75 20 13 - 90 24 15 ns 3.0 - 7.0 - 7.0 - 7.0 pF - 50 - - - - pF CI VI = 0 V or VCC Figure 1 and 3 Input capacitance CPD Power dissipation capacitance (per one channel) VI = 0 V or VCC * VCC = 3.3 ± 0.3 V tr 1An or 2An 10% tf VCC 90% 50% t PHL 1Yn or 2Yn 50% 10% t PZL GND tPLH VCC 50% 1OE or 2OE VCC 50% 1Yn or 2Yn 90% t THL VOL t PHZ t PZH t TLH GND t PLZ VOH 1Yn or 2Yn 50% GND Figure 1.
