MC74HC373ADWR2G ON Semiconductor

MC74HC373A Octal 3-State Non-Inverting Transparent Latch HighPerformance SiliconGate CMOS The MC74HC373A is identical in pinout to the LS373. The device MC74HC373A Design Criteria Value Units Internal Gate Count* 46.5 ea Internal Gate Propagation Delay 1.5 ns Internal Gate Power Dissipation 5.0 W Speed Power Product 0.0075 pJ *Equivalent to a twoinput NAND gate. MAXIMUM RATINGS Symbol Parameter Value Unit This device contains protection circuitry to guard against damage V DC Supply Voltage (Referenced to GND) 0.5 to +7.0 V CC due to high static voltages or electric V DC Input Voltage (Referenced to GND) 0.5 to V + 0.5 V in CC fields. However, precautions must be taken to avoid applications of any V DC Output Voltage (Referenced to GND) 0.5 to V + 0.5 V out CC voltage higher than maximum rated I DC Input Current, per Pin 20 mA in voltages to this highimpedance cir- I DC Output Current, per Pin 35 mA cuit. For proper operation, V and out in V should be constrained to the out I DC Supply Current, V and GND Pins 75 mA CC CC range GND (V or V ) V . in out CC P Power Dissipation in Still Air, SOIC Package 500 mW D Unused inputs must always be TSSOP Package 450 tied to an appropriate logic voltage level (e.g., either GND or V ). CC T Storage Temperature 65 to +150 C stg Unused outputs must be left open. T Lead Temperature, 1 mm from Case for 10 Seconds C L (SOIC, SSOP or TSSOP Package) 260 Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected.
