TECHNICAL DATA IW4043B Quad 3-State R/S Latches High-Voltage Silicon-Gate CMOS The IW4043B types are quad cross-coupled 3-state CMOS NOR latces. Each latch has a separate Q output and individual SET and RESET inputs. The Q outputs are controlled by a common ENABLE input. A logic “1” or high on the ENABLE input connects the latch states to the Q outputs. A logic “0” or low on the ENABLE input disconnects the latch states from the Q outputs, resulting in an open circuit condition on the Q outputs. The open circuit feature allows common busing of the outputs. • 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): 1.0 V min @ 5.0 V supply 2.0 V min @ 10.0 V supply 2.5 V min @ 15.0 V supply ORDERING INFORMATION IW4043BN Plastic IW4043BD SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs PIN 13 = NO CONNECTION PIN 16=VCC PIN 8= GND Outputs S R OE Q X X L High Impedance L L H No change L H H L H L H H H H H H X = don’t care Rev. 00 IW4043B MAXIMUM RATINGS* Symbol Parameter Value Unit -0.5 to +20 V VCC DC Supply Voltage (Referenced to GND) VIN DC Input Voltage (Referenced to GND) -0.5 to VCC +0.5 V DC Output Voltage (Referenced to GND) -0.5 to VCC +0.5 V VOUT IIN DC Input Current, per Pin ±10 mA PD Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ 750 500 mW PD Power Dissipation per Output Transistor 100 mW -65 to +150 °C 260 °C Tstg TL 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, VIN 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 VCC). Unused outputs must be left open.
