ELM307 Camera Control Description 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. A low level at this input immediately caus.

ELM304 NTSC Video Generator Description The ELM304 is a low-cost NTSC video signal generator in an 8 pin package. Requiring only an external crystal and a few passive components, this circuit produces a stable raster that is suitable for a variety of video applications. The ELM304 can be ‘programmed’ to generate either a solid white raster or a four-level gray scale pattern simply by changing the logic level at the mode input pin. A supplied internal pullup resistor further simplifies the circui.

ELM303 Camcorder Time–Lapse Control Description The ELM303 is a specialized circuit for creating time-lapse videos on suitably equipped camcorders. The camcorder to be controlled must have a Control L (LANC) port, and also be capable of responding to power control signals. This is usually only available with the mini DIN connectors, and not the 2.5mm stereo plug interfaces. The ELM303 provides intervals of 10 minutes to 24 hours between recordings, without requiring any external timing component.

Camera Control

ELM307 Camera Control Description 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. A low level at this input immediately causes an output at the Camera pin (controlling the shutter) that lasts for the duration set by PW. Further triggering is inhibited until an www.DataSheet4U.com additional period (set by Delay) passes, allowing time for the film to advance or for the digital image to be stored. To help with setup, the circuit has a test mode in which the Camera output is blocked, and the LED is instead energized. Toggling between the test mode and the run mode is accomplished with the single pushbutton input, as is the power on and off. Features • 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 • High current drive outputs - up to 25mA Connection Diagram PDIP and SOIC (top view) VDD Delay 1 2 3 4 8 7 6 5 VSS Camera LED Trigger Applications • Security camera control • Candid shots of animals or people • Time lapse photography • Remote triggering of c.
