HTC151 LED FLASHER
1.0 General description.
This circuit is designed to work as led flasher. LED's
sequentially turn on and off according to the part used. D[0:2]
inputs are used to control flashing frequency. There are seven
different frequencies selectable. See D[0:2] input settings
versus frequency table. HTC151 Can control up to 64 LED's
(eight LED's per output @ 3mA each).
Features
 Minimum number of external components.
Easy selection of alternating frequency.
Predictability and design ease.

Abbreviations used: O - output, I - input, P - power.

Please note that those values are for reference only. Actual frequency can vary up to 10 percent
depending upon VDD voltage and operational temperature.
2.0 Functional description.
HTC151 has two variations determined by part number. Common to all models of HTC151 is
alternating frequency selection and pin-out. Please refer to "Typical connection diagram" used as
reference. Frequency is changed when state of D [0:2] input pins change. Refer to "Frequency
selection per D [0:2]" table for frequency selection. Note that Dip Switch could be omitted by hard
wiring D [0:2] inputs to GND or VDD. This section describes operation of each HTC150 model
separately. Each part uses different alternating algorithm.

States:
1. LED1 is turned on and all others are off.
2. LED2 is turned on and all others are off.
3. LED3 is turned on and all others are off.

State is changed at frequency selected by D[0:2].
The circuit will change the flashing frequency as soon as DO, D1 or D2 input pin state is changed.
From that time next LED's start flashing at new frequency. The first LED starts over with the new
frequency and it continues until the D0, D1 or D2 input pin state is changed again.
