TECHNICAL DATA KK74LV245 OCTAL BUS TRANSCEIVER; 3-State The KK74LV245 is a low-voltage Si-gate CMOS device and is pin and function compatible with KK74HCT245. The KK74LV245 is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The KK74LV245 features an output enable (OE) input for easy cascading and a send/receive (DIR) input for direction control. OE controls the outputs so that the buses are effectively isolated. • Output voltage levels are compatible with input levels of CMOS, NMOS and TTL ICS • Supply voltage range: 1.2 to 3.6 V • Low input current: 1.0 µА; 0.1 µА at Т = 25 °С • Output Current: 8 mA at VCC = 3.0 V • High Noise Immunity Characteristic of CMOS Devices N SUFFIX PLASTIC DIP 20 A1 A2 A DATA PORT A3 A4 A5 A6 A7 DIR OE DW SUFFIX SO 20 1 ORDERING INFORMATION KK74LV245D Plastic DIP KK74LV245DW SOIC TA = -40° to 125° C for all packages LOGIC DIAGRAM A0 1 PIN ASSIGNMENT 2 18 3 17 4 16 5 15 6 14 7 13 8 12 9 11 B0 B1 B2 B3 B4 B DATA PORT B5 B6 B7 1 DIR 1 20 VCC A0 2 19 OE A1 3 18 B0 A2 4 17 B1 A3 5 16 B2 A4 6 15 B3 A5 7 14 B4 A6 8 13 B5 A7 9 12 B6 10 11 B7 GND 19 FUNCTION TABLE PIN 20=VCC PIN 10 = GND Inputs Inputs/outputs OE DIR A B L L A=B input L H input B=A H X Z Z H= high level L = low level X = don’t care Z = high impedance 1 KK74LV245 MAXIMUM RATINGS* Symbol VCC Parameter DC supply voltage Value Unit -0.5 to +5.0 V 1 DC Input diode current ±20 mA 2 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 IIK * IOK * IO * 3 PD Tstg TL 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 KK74LV245 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 0.09 - 0.1 0.1 0.1 0.09 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 (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 KK74LV245 AC ELECTRICAL CHARACTERISTICS (CL=50 pF, tr=tf=6.0 ns, RL = 1 kΩ) 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 , An to Bn, Bn to An VI = 0 V or VCC Figure 1 1.2 2.0 * - 100 23 14 - 125 28 18 - 140 34 21 ns tPHZ, tPLZ Propagation delay, OE, DIR to An, Bn VI = 0 V or VCC Figure 2 1.2 2.0 * - 120 30 20 - 140 37 24 - 160 43 28 ns tPZH, tPZL Propagation delay, OE to An, Bn VI = 0 V or VCC Figure 2 1.2 2.0 * - 120 28 17 - 140 35 21 - 160 43 26 ns tTHL, tTLH Output Transition Time, Any Output VI = 0 V or VCC Figure 1 1.2 2.0 * - 60 16 10 - 75 20 13 - 90 24 15 ns Input capacitance For inputs 01,19 3.0 - 7.0 - - - - pF CI/О Input/output capacitance For inputs/ outputs 02-09, 11-18 3.0 - 20 - - - - pF CPD Power dissipation capacitance (per one channel) VI = 0 V or VCC - 50 - - - - pF CI * VCC = 3.3 ± 0.3 V tr A (B) tf VCC 90% 50% 10% GND tPLH DIR 50% OE 50% t PHL B (A) 50% 10% * 90% 50% VOL VOH GND Figure 2.
