HD151012 - 8-bit Binary Programmable Counter with Synchronous Preset Enable

Description

The HD151012 has 8-bit binary down counter and D-type Flip Flop.

The counter can set up to max 256 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.

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) HD151012 Function Table Control Inputs CLR H X L H PR H X H L SPE H L.
  • Mode Generally count Synchronous preset Initialize of Q output Initialize of Q output Operation.

HD151012 8-bit Binary Programmable Counter with Synchronous Preset Enable ADE-205-132 (Z) Preliminary 1st. Edition Mar. 1996 Description The HD151012 has 8-bit binary down counter and D-type Flip Flop. The counter can set up to max 256 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.
