MC74HCT241A Octal 3-State Noninverting Buffer/Line Driver/ Line Receiver with LSTTL-Compatible Inputs http://onsemi.com High−Performance Silicon−Gate CMOS The MC74HCT241A is identical in pinout to the LS241. This device may be used as a level converter for interfacing TTL or NMOS outputs to High−Speed CMOS inputs. The HCT241A is an octal noninverting buffer/line driver/line receiver designed to be used with 3−state memory address drivers, clock drivers, and other bus−oriented systems. The device has non−inverted outputs and two output enables. Enable A is active−low and Enable B is active−high. The HCT241A is similar in function to the HCT244. See also HCT240.

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 v (Vin or Vout) v 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. _C 260 300 Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. †Derating — Plastic DIP: – 10 mW/_C from 65_ to 125_C Ceramic DIP: – 10 mW/_C from 100_ to 125_C SOIC Package: – 7 mW/_C from 65_ to 125_C ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎ RECOMMENDED OPERATING CONDITIONS Symbol VCC Vin, Vout Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage, Output Voltage (Referenced to GND) TA Operating Temperature, All Package Types tr, tf Input Rise and Fall Time (Figure 1) Min Max Unit 4.5 5.5 V 0 VCC V – 55 + 125 _C 0 500 ns DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) Guaranteed Limit VCC V – 55 to 25_C v 85_C v 125_C 4.5 5.5 2 2 2 2 2 2 Symbol VIH Parameter Minimum High−Level Input Voltage Test Conditions Vout = 0.1 V or VCC – 0.1 V |Iout| v 20 μA VIL Maximum Low−Level Input Voltage Vout = 0.1 V or VCC – 0.1 V |Iout| v 20 μA 4.5 5.5 0.8 0.8 0.8 0.8 08 0.8 V VOH Minimum High−Level Output Voltage Vin = VIH or VIL |Iout| v 20 μA 4.5 5.5 4.4 5.4 4.4 5.4 4.4 5.4 V Vin = VIH or VIL |Iout| v 6 mA 4.5 3.98 3.84 3.7 Vin = VIH or VIL |Iout| v 20 μA 4.5 5.5 0.1 0.1 0.1 0.1 0.1 0.1 Vin = VIH or VIL |Iout| v 6 mA 4.5 0.26 0.33 0.4 VOL Maximum Low−Level Output Voltage Unit V V Iin Maximum Input Leakage Current Vin = VCC or GND 5.5 ± 0.1 ± 1.0 ± 1.0 μA IOZ Maximum Three−State Leakage Current Output in High−Impedance State Vin = VIL or VIH Vout = VCC or GND 5.5 ± 0.5 ± 5.0 ± 10 μA ICC Maximum Quiescent Supply Current (per Package) Vin = VCC or GND Iout = 0 μA 5.5 4 40 160 μA ΔICC Additional Quiescent Supply Current Vin = 2.4 V, Any One Input Vin = VCC or GND, Other Inputs lout = 0 μA 1.
