Quadruple static decade counters
DESCRIPTION The HEF4737B and HEF4737V are static quadruple decade counters for frequencies from 0 to 10 MHz. The counters are supplied with an extra overload flip-flop giving a total count capability of 19 999. The counter has the following inputs and outputs: a count input (CP), an asynchronous reset input (MR), an asynchronous preset input (PL), a transfer input (T), an output enable input (EO) (which controls the BCD outputs), the digit select inputs (SA, SB, SC) (which perform selection of the contents of the latches to the 3-state BCD outputs (O0 to O3)), and the carry outputs (CO2 to CO5) (which give the carry signals of the decades except from the first decade).
HEF4737B HEF4737V
The complementary MOS structure gives the devices very low stand-by and operating dissipation. Operating from a single supply voltage all outputs can drive one standard TTL input without interface circuitry under all specified operating conditions. The BCD digit outputs are LOCMOS 3-state outputs. The high impedance off-state feature allows common busing of the outputs. The count...
