Three-Bit Parity Circuit

Summary: The B130 is a special-purpose logic module designed to compute parity (odd or even) for flip-flop register contents. It features high-speed logic with complementary outputs and a minimum time delay, and it can also serve as a 4-input OR gate.

Key technical specifications include:

• Performance: Typical propagation delay of 15 nsec.
• Inputs: Requires a 2-ma load shared among ground inputs; total load per line at ground is 2⅔ ma.
• Outputs: Capable of driving 10 ma at ground plus a built-in clamped load (7 ma at -3 V).
• Power Requirements: +10 V (49 ma) and -15 V (92 ma).
• Applications: Includes an indicator output for use with W020 Indicator Connector Boards.
