Product Use

This Solid State Device is especially developed for Automotive use as high speed electronic 555 Timer replacement.

The IC package pin out is identical to the popular 555 Timer IC.

The OKA555 Timer can be used as a drop in replacement for NE555, KA555, SE555, LM555, NA555, SA555.

In constant ON applications it can carry up to 200 miliAmperes (Sink or Source).

Millions of these devices have been reliably used since September 2014 in following applications:

• Monostable (One-Shot)
• Astable (Oscilator)
• Instrument Illumination Brightness Control PWM
• Delay OFF Timer
• Delay ON Timer
• ON on Power Up and then OFF Timer
• Solo Flasher
• Dual Flasher
• Bistable (Flip-Flop)
• Mechanical Switch Contact De-bouncer
• Tachometer
• Speed Warning Device

Features

• Power Supply Voltage up to 18V
• −55 to +125 °C operating temperature
• PDIP-8 Package
• Output Current − Continuous 200mA
• Individually tested prior shipment
