Technical content

High-Voltage Silicon-Gate CMOS The SL4049 B is inverting hex buffers and feature logic -level conversion using on ly one supply (voltage (V CC). The input-signal high level (VIH) can exceed the V CC supply voltage when these devices are used for logic-level conversions. These devices are intended for use as CMOS to DTL/TTL converters.

  • Operating Voltage Range: 3.0 to 18 V
  • Maximum input current of 1 µA at 18 V over full package- temperature range; 100 nA at 18 V and 25°C
  • Noise margin (over full package temperature range): 0.5 V min @ 5.0 V supply 1.0 V min @ 10.0 V supply 1.0 V min @ 15.0 V supply
  • High-to-low level conversion

Functional operation should be restricted to the Recommended Operating Conditions. +Derating - Plastic DIP: - 10 mW/°C from 65° to 125°C The IW4049UB has high-to-low level voltage conversion capability but not low -to-high level; therefore it is recommended that VIN ≥ VCC RECOMMENDED OPERATING CONDITIONS Symbol Parameter Min Max Unit VCC DC Supply Voltage (Referenced to GND) 3.0 18 V VIN DC Input Voltage (Referenced to GND) VCC 18 V VOUT DC Output Voltage (Referenced to GND) 0 VCC V TA Operating Temperature, All Package Types -55 +125 °C ** The SL4049B has high-to-low level voltage conversion capability but not low -to-high level; therefore it is recommended that VIN ≥ VCC This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high -impedance circuit. For proper operation, V IN 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 V CC). Unused outputs must be left open.
