Product Code : SCL-EELE-12665
Indian Lab Suppliers supplies the 12 Bit Even Parity Generator and 13 Bit Even Parity Checker (Product ID: 12665) as part of its electronics engineering lab equipment range. It generates an even parity bit for 12 data bits and checks even parity on a 13-bit word, using XOR logic.
Quick Answer
Twelve data bits are set on toggle switches and the generator produces the parity bit that makes the total number of 1s even. The checker takes 13 bits (the 12 data bits plus the parity bit) and its output shows whether the word still has even parity, which is how a single-bit error is detected. The logic uses three 7486 quad XOR ICs, with 13 toggle switches and 15 LEDs (13 for input bits, 2 for outputs). The board runs from 230 V, 50 Hz mains with an on/off switch, fuse and jewel light; a TTL logic probe specification is listed, so please confirm at quotation whether the probe is supplied.

Frequently Asked Questions
How is the even parity bit formed?
By XOR-ing the 12 data bits, so the total count of 1s including the parity bit is even.
How many bits does the checker take?
13: the 12 data bits and the parity bit.
Which ICs are used?
Three 7486 quad XOR gate ICs.
