Fault-Protected, High-Voltage, Single 4-to-1/Dual 2-to-1 Multiplexers

General Description The MAX4534 (single 4-to-1) and MAX4535 (dual 2-to- 1) fault-protected multiplexers operate with ±4.5V to ±20V dual supplies or a +9V to +36V single supply. These multiplexers feature fault-protected inputs, railto-rail signal-handling capability, and overvoltage clamping at 1

Real time 5-decade counter

DESCRIPTION The HEF4534B is a 5-decade ripple counter. The binary outputs of the decade counters are time-multiplexed by an internal scanner on four BCD outputs (O0 to O3). The selected decade is indicated by a logic HIGH on the appropriate digit select output (OS0: units, 1; OS1: tens, 10;
