| 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 u A temperature range ;100 nA at 18 V and 25 C Noise margin (over full package temperature range): 1.0 V min @ 5.0 V supply 2.0 V min @ 10.0 V supply 2.5 V min @ 15.0 V supply 16 16 DIP - 16 SOP - 16 Package Logic Diagram Pin Assignment A1 3 2 Y1 Vcc Y1 A1 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 NC Y6 A1 A2 5 4 Y2 Y2 A2 NC Y5 A5 Y4 A4 A3 7 6 Y3 Y3 A3 GND A4 9 10 Y4 NC = NO CONNECTION A5 11 12 Y5 Function Table Inputs A H L Output Y L H A6 14 15 Y6 PINS 13, 16 = NO CONNECTION PIN 1 = V CC PIN 8 = GND BEIJING ESTEK ELECTRONICS CO.,LTD 1 IW4049B Absolute Maximum Ratings Symbol VCC V IN VOUT IIN PD PD Tstg TL Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin Power Dissipation in Still Air, Plastic DIP Value -0.5 to 20 to +18 V -0.5 to VCC+0.5 + 10 750 500 100 -65 to 150 260 Unit V V V mA mW mW C C SOIC Package Power Dissipation per Output Transistor Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) 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) 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.
