MC14531B
The MC14531B 12–bit parity tree is constructed with MOS P–channel and
N–channel enhancement mode devices in a single monolithic structure. The
circuit consists of 12 data–bit inputs (D0 thru D11), and even or odd parity
selection input (W) and an output (Q). The parity selection input can be
considered as an additional bit. Words of less than 13 bits can generate an
even or odd parity output if the remaining inputs are selected to contain an
even or odd number of ones, respectively. Words of greater than 12–bits can
be accommodated by cascading other MC14531B devices by using the W
input. Applications include checking or including a redundant (parity) bit to a
word for error detection/correction systems, controller for remote digital
sensors or switches (digital event detection/correction), or as a multiple input
summer without carries.
