Quadruple static decade counters
HEF4737B
HEF4737V
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).
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 counters are supplied with asynchronous
reset and preset to 19 999 facilities making them suitable
for counter and time base applications. All carry signals
are available except from the first decade.
Schmitt-trigger action in the inputs makes the circuit highly
tolerant to slower input rise and fall times.
Recommended supply voltage range for HEF4737B is 3 to
15 V and for HEF4737V is 4,5 to 12,5 V.
