The 74LS373 consists of eight latches with 3-state outputs for bus organized system applications. The flip-flops appear transparent to the data.

The Exclusive OR gates are monolithic complementary MOS (CMOS) integrated circuits constructed with N-Channel and P-Channel enhancement mode transistors. All inputs are protected against static discharge with diodes to VDD and VSS.

The 4077 is a quad 2-input EXCLUSIVE-NOR gate. The outputs are fully buffered for the highest noise immunity and pattern insensitivity to output impedance. The 4077 operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.

The BT139 is a TRIAC thyristor, which is a type of semiconductor device that can use to control alternating current (AC) power. TRIAC thyristor BT139 is a four-quadrant device, meaning that it can conduct current in either direction. The BT139 has a peak inverse voltage (PIV) of 800 volts and a current rating of 16 amperes. It is a sensitive gate triac, meaning that it can be triggered with a low gate current. The on-state voltage drop of the BT139 is 1.2 volts. Here are some of the key features of the BT139-800E 4 Quadrant TRIAC:
