CD40257B

The CD40257B is a data selector/multiplexerfeaturing three-state outputs which can interface directly with and drive data lines of Ixus-oriented systems.It is supplied in 16-lead hermeic dual-in-line ceramic flat packages(K suffix) and in chip form(H suffix).

Features of of the CD40257B are:(1)3-state outputs; (2)standardized, symmetrical output characteristics; (3)100% tested for quiescent current at 20 V; (4)5 V , 10 V and 15 V parametric ratings; (5)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 CD40257B 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.
