CD4093B

The CD4093B is designed as CMOS quad 2-input NAND schmitt trigger which consists of four schmitt trigger circuits. Eacj circuit functions as a two input NAND gate with schmitt trigger action on both inputs. The gate switches at different points for positive and negative going signals.

CD4093B has nine features. (1)schmitt trigger action on each input with no external components. (2)Hysteresis voltage typically 0.9V at Vdd=5V and 2.3V at Vdd=10V. (3)Noise immunity greater than 50%. (4)No limit on input rise and fall times. (5)Standardized, symetrical output characteristics. (6)100% tested for quiescent current at 20V. (7)CD4093B Maximum input current of 1uA at 18V over full package temperature range, 100nA at 18V and 25°C. (8)5V, 10V and 15V parametric ratings. (9)Meets all requirements of JEDEC standard No.13B. Those are all the main features.

Some absolute maximum ratings have been concluded into several points as follow. (1)Its DC supply voltage range would be from -0.5V to 20V. (2)CD4093B's input voltage range all inputs would be from -0.5V to Vdd+0.5V. (3)Its DC input current any one input would be +/-10mA. (4)Its package thermal impedanc ewould be 80°C/W for E package and would be 86°C/W for M package and would be 76°C/W for NS package. (5)Its device dissipation per output transistor would be 100mW. (6)Its operating temperature range would be from -55°C to 125°C. (7)Its storage temperature range would be from -65°C to 150°C. (8)Its lead temperature would be 265°C. CD4093B should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics are concluded as follow. (1)CD4093B's quiescent device current would be typ 0.02uA and max 1uA at Vin=0.5V and Vdd=5V. (2)Itspositive trigger threshold voltage would be min 2.2V and typ 2.9V min and would be typ 2.9V and max 3.6V max at Vdd=5V. (3)Its negative trigger threshold voltage would be 0.9V and typ 1.9V min and would be typ 1.9V and max 2.8V max at Vdd=5V. And so on.
