ELM460 Impossible Oscillator Description The ELM460 is a complete astable oscillator circuit in an 8 pin package. The circuit (impossibly!) requires no external components to operate, as all timing is generated internally. Immediately after power-up, the ELM460 begins to oscillate continuously at a
5 PIN SOP HIGH SPEED 1Mbit/s TRANSISTOR PHOTOCOUPLER Features • High speed 1Mbit/s • High isolation voltage between input and output (Viso=3750 Vrms ) • High CMR 15KV/us at VCM=1500V (ELM453) • Guaranteed performance from 0° C to 70° C • Wide operating temperature range of -40° C to 85

ELM405 Rotary Decoder - 3 wire 4x Interface Description The ELM405 is an 8 pin integrated circuit that is used to convert the output from a rotary encoder into three signals (chip select, clock and up/down) that can be used to control various devices. The low power CMOS technology used ensures that
ELM415 Up/Down Interface Description Many modern control circuits use the value from a digital counter to directly determine a setting or position. Manipulating this value under computer control is not difficult, but when one has to interface with a human operator, several other factors must be cons
ELM412 Piezo Element Driver Description The ELM412 is an 8 pin oscillator circuit for driving piezo-electric elements. With the exception of one external resistor, all of the circuitry required to drive a typical piezo ‘bender’ is contained within this chip. This circuit allows the user to selec
