DIGITAL ELECTRONICS UNITS
BHI-ED-1158
Qty Comments

Designed to the requirements of revised Nuffield 'A' level physics, these units are all based on CMOS integrated circuits. CMOS devices have advantages over TTL in that power requirements are lower so longer battery life can be expected, and the units will operate from any smoothed d.c. Supply of between 4.5 and 9V.
Whilst each board has independent power supply connections, they may be cascaded and run from a single power source. All the logic outputs are connected to L.E.D. Indicators which are activated when the output goes high. Inputs are held low when not connected. All units are protected against damage from reversal power supply connections.
