CD40208BE

The CD40208BE is designed as a 4x4 multiport register containing four 4-bit registers, write address decoder, two separate read address decoders, and two 3-state output buses.

CD40208BE has many features. (1)High voltage types (20V rating). (2)CD40208BE One input and two output buses. (3)Unlimited expansion in bit and word directions. (4)Data lines have latched inputs. (5)3-state outputs. (6)Separate control of each bus, allowing simultaneous independent reading of any of four registers on bus A and bus B and independent writing into any of the four registers. (7)100% tested for quiescent current at 20V. (8)Standardized, symmetrical output characteristics. (9)5V, 10V and 15V parametric ratings. (10)Meets all requirements of JEDEC tentative standards No.13B, "standard specifications for description of "B" series CMOS devices". And so on.

Some absolute maximum ratings have been concluded into several points as follow. (1)CD40208BE's DC supply voltage range would be from -0.5V to +20V. (2)Its 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 operating temperature range would be from -55°C to 125°C. (5)Its storage temperature range would be from -65°C to 150°C. (6)Its lead temperature during soldering would be 265°C. CD40208BE should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some CD40208BE electrical characteristics are concluded as follow. (1)CD40208BE's supply current would be max 10uA. (2)Its input leakage current would be min -100nA and max 100nA. (3)Its output voltage would be max 50mV for low and would be min 14.95V for high. (4)Its output current sink would be min 0.53mA at Vdd=5V and would be min 1.4mA at Vdd=10V and would be min 3.5mA for Vdd=15V. (5)CD40208BE's output current source would be max -0.53mA at Vdd=5V and Vout=4.6V and would be max -1.8mA at Vdd=5V and Vout=2.5V. And so on.
