Dual BCD Programmable Counter
with Synchronous Preset Enable
ADE-205-100(Z)
Rev 0
April 1995
The HD151011 has BCD decimal two digits down counter and D-type Flip Flop. The counter can set up to
max 99 counts and synchronous preset (SPE) input can preset the data. When the count value is 0, the next
clock pulse presets the data to invert the output. D-type Flip Flop takes the counter output as clock pulse,
whose data is transferred to output at the rise edge. It is applied to generate AC signal for STN type liquid
crystal and general-use divider.
Features
• High speed operation
tpd (CLK or CLK to Q) = 35 ns (typ)
• High output current
Fanout of 10 LS TTL Loads
• Wide operating voltage
Vcc = 2 to 6 V
• Low supply current (Ta = 25°C)
Icc (Static) = 4 µA (max)
