CD4504B

The CD4504B hex voltage level-shifter consists of six circuits which shift input signals from the Vcc logic level to the VDD logic level.To shift TTL signals to CMOS logic levels, the SELECT input is at the Vcc HIGH logix state.When the SELECT input is at LOW logic state,each circuit translates signals from one CMOS level to another.

Features of the CD4504B are:(1)independent of power-supply sequence considerations-Vcc can exceed VDD; (2)yp and down level-shifting capability; (3)shiftable input threshold for either CMOS or TTL compatibility; (4)standardized symmetrical output characteristics; (5)100% tested for quiescent current at 20 V; (6)5 V , 10 V and 15 V parametric ratings; (7)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 CD4504B 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.
