Binary-to-Octal Decoder Type R151

Summary: The R151 is a binary-to-octal decoder that converts information from three flip-flops into one of eight distinct outputs. When the enable input is grounded, the selected output line is grounded, while the other seven outputs remain at -3V. If the enable input is at -3V, all outputs remain at -3V.

Key technical specifications include:

• Timing: Typical transition times are 75 nsec for rise and 60 nsec for fall; input signals require a 100 nsec minimum duration.
• Input/Output Load: Detailed current load specifications are provided for inputs and outputs, noting that outputs have permanently attached 2-ma clamped load resistors.
• Power: Requires +10V (0.9 ma) and -15V (32 ma).
• Operation: The document includes a complete truth table mapping the binary inputs (J, H, E, F, K, L, D) to the octal outputs (M, N, P, R, S, T, U, V).
