LED FLASHERS
1.0 General description.
This circuit is designed to work as led flasher. LED's
sequentially turn on and off according to part used. D0 and D1
inputs are used to control flashing frequency. There are four
different frequencies selectable. See D[0:1] versus frequency
table. HTC150 Can control up to 32 LED's (eight LED's per
output @ 3mA each).
Features
Minimal external components.
Easy selection of alternating frequency.
Predictability and design ease.

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

2.0 Functional description.
HTC150 has several variations determined by part number. Common to all models of HTC150 is
alternating frequency selection and pin-out. Please refer to "Typical connection diagram" used as
reference. Frequency is changed when state of D[0:1] input pins change. Refer to "Frequency
selection per D[0:1]" table for frequency selection. Note that Dip Switch could be omitted by hard
wiring D[0:1] inputs to GND or VDD. This section describes operation of each HTC150 model
separately. Each part uses different alternating algorithm.
HTC150A
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.
4. LED4 is turned on and all others are off.
State is changed at frequency selected by D[0:1].

The circuit will change the flashing frequency as soon as the DO or D1 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 or D1 state is changed again.
