IW4049B Description The IW4049B is hex buffers and feature logic-level conversion using only one supply (voltage Vcc).The input- signal high (Vih) can exceed the Vcc supply voltage when these devices are used for logic -level conversions. These devices are intended for use as CMOS to DTL/TTL converters Features Operating Voltage Range: 3.0 to 18 V at 18 V over full packageMaximum input current of 1 utemperature range ;100 nA at 18 V and 25 C A Noise margin (over full package temperature range): 1.0 V min @ 5.0 V supply 2.0 V min @ 10.0 V supply 16 16 SOP - 16 DIP - 16 2.5 V min @ 15.0 V supply Package Logic Diagram Pin Assignment A1 A2 A3 A4 A5 A6 3 5 7 2 4 6 9 10 11 12 14 15 Y1 Y2 Y3 Vcc 1 16 NC Y1 2 15 Y6 A1 3 14 A1 Y2 4 13 NC A2 5 12 Y5 Y3 6 11 A5 A3 7 10 Y4 GND 8 9 A4 Y4 NC = NO CONNECTION Y5 Function Table Y6 Inputs Output A Y H L L H PINS 13, 16 = NO CONNECTION PIN 1 = V CC PIN 8 = GND BEIJING ESTEK ELECTRONICS CO.,LTD 1 IW4049B Absolute Maximum Ratings Symbol Parameter VCC DC Supply Voltage (Referenced to GND) V IN DC Input Voltage (Referenced to GND) VOUT DC Output Voltage (Referenced to GND) IIN DC Input Current, per Pin PD Power Dissipation in Still Air, Plastic PD SOIC Package Power Dissipation per Output Transistor Tstg TL DIP Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) Value Unit -0.5 to 20 V to +18 V -0.5 to VCC+0.5 V V +- 10 750 500 mW 100 mW -65 to 150 °C 260 °C mA 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, V IN and V OUT should be constrained to the range GND (VIN or VOUT)ﾣ 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.
