CD4028B

The CD4028B types are BCD-to-decimal or binary-to-octal decoders consisting of budffering on all 4 inputs, decoding-logic gates, and 10 output buffers, A BCD code applied to the four inputs, A to D, results in a high level at the selected one of 10 decimal decoded ouputs.

Features of the CD4028B are:(1)100% tested for quiescent current at 20 V; (2)high decoded output drive capability; (3)5 V , 10 V and 15 V parametric ratings; (4)BCD-to-decimal decoding or binary-to-octal decoding; (5)Schmitt-triggered clock inputs; (6)maximum input current of 1 uA at 18 V over full package-temperature range;100 nA at 18 V and 25.

The absolute maximum ratings of the CD4028B can be summarized as:(1): DC supply-voltage range(VDD) is -0.5 V to +20 V(voltages referenced to Vss terminal); (2): input voltage range, all inputs is -0.5 V to VDD+0.5 V; (3): DC input current, any one input is ±10 mA; (4): operating temperature range(Ta) is -55 to +125; (5): storage temperature range(Tstg) is -65 to +150.
