The 100360 is a dual parity checker/generator. Each half has nine inputs; the output is HIGH when an even number of inputs are HIGH. One of the nine inputs (Ia or Ib) has the shorter through-put delay and is therefore preferred as the expansion input for generating parity for 16 or more bits. The 100360 also has a Compare (C) output which allows the circuit to compare two 8-bit words. The C output is LOW when the two words match, bit for bit. All inputs have 50 k pull-down resistors.
