MIL-M-38510-307 Microcircuits, Digital, Bipolar Low-Power Schottky Ttl, Decoders, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, low-power Schottky TTL, decoder microcircuits. Two product assurance classes and a choice of case outlines and lead finishes are provided for each type and are reflected in the complete part number. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.

MIL-M-38510/307D

DEVICE TYPE 04

NOTES:

1.        BI/RBO is wire-OR logic serving as blanking input (BI) and/or ripple-blanking output (RBO).  The blanking input must be open or held at a high logic level when output functions 0 through 15 are desired and ripple- blanking input (RBI) must be held open or at a high logic level during the decimal 0 input, X = input may be

high or low.

2.        When a low logic level is applied to the blanking input (forced condition) all segment outputs go to a high logic level regardless of the state of any other input condition.

3.    When ripple-blanking input (RBI) is at a low logic level, lamp test input is at high logic level and A = B = C = D

= low logic level, all segment outputs go to a high logic level and the ripple-blanking output goes to a low logic level (response condition).

4.        When blanking input/ripple-blanking output is open or held at a high logic level, and a low logic level is applied to lamp-test input, all segment outputs go to a low logic level.
