SP1404BW - GEC Plesset

SP1404BW HIGH VOLTAGE INTERFACE

(Fig.2) OUTPUT 5 INPUT 5 The SP1404 operates as a power amplifier interfacing from a voltage-level sensitive input to a high-current output switch. 7 0V ELECTRONIC 0V EXCHANGE 8 The input threshold is TTL-compatible, with a low input current DP14 requirement enabling one standard TTL output to drive many interfaces. The low input current requirement also ma.

Features

t the Figure 1: Pin connections (viewed from underside) SP1404 inputs. Each element of the device performs as inverting function, i.e. a low voltage level on the input causes a high current in the BIAS CHAIN output. If the input is left open-circuit, the output will be off and FOR ALL 5 ELEMENTS the output current will be zero. +VCC The isolation of the integrated circuit is biased to the more negative of the two earth points by diodes D1 and D2 so that www.DataSheet4U.com differences of up to (VCC- 1) volts can be tolerated between the ‘noisy’ exchange earth and the ‘quiet’ electronic earth. .
