ELM307 Datasheet Camera Control

Manufacturer: ELM Electronics

Overview: ELM307 Camera Control.

Datasheet Details

The ELM307 is a retriggerable one-shot circuit that has been designed for electronically controlling the shutter of a film or digital still camera.

The circuit provides a variable pulse width timer, a variable delay reset timer, power control, and an LED status drive all in an 8 pin package.

In operation, a monitored signal (alarm contact, audio signal, oscillator signal, etc.) is applied to the circuit’s Trigger input.

Low power CMOS design - typically 1mA at 5V.
No external timing elements required.
Test mode assists with setup.
Single pushbutton control.
Auto power off saves batteries.
LED output shows status.
