The DAC0808 is an 8-bit monolithic digital-to-analog converter (DAC) featuring a full scale output current settling time of 150 ns while dissipating only 33 mW with ±5V supplies.

Each circuit functions as an inverter, but because of the Schmitt action, it has different input threshold levels for positive-going (VT+) and negative-going (VT–) signals. These circuits are temperature compensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals.

The CD4016BC is a quad bilateral switch intended for the transmission or multiplexing of analog or digital signals.

These 8-bit shift registers feature gated serial inputs and an asynchronous clear. A low logic level at either input inhibits entry of the new data, and resets the first flip-flop to the low level at the next clock pulse, thus providing complete con- trol over incoming data.

The SN75176B differential bus transceiver provides an interface to RS485 multipoint transmission lines.

The TL431 is a three−terminal programmable shunt regulator diode.

LM324 is a 14pin IC consisting of four independent operational amplifiers (op-amps) compensated in a single package. Op-amps are high gain electronic voltage amplifier with differential input and, usually, a single-ended output.
