MIL-M-38510-319 Microcircuits, Digital, Low-Power Schottky Ttl, 4 By 4 Register File, Cascadable, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, Schottky TTL, low-power, 4 by 4 register file 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.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-3851O/319C

Device type O1

Write function table (see notes A, B, and C)                                Read function table (see notes A and D)

Write inputs                                 Word                                          Read inputs                                   Outputs

NOTES:

A.  H = high level, L = low level, x = irrelevant, z = high impedance (off)

B.  (Q = D)  -  The four selected internal flip-flop outputs will assume the states applied to the four external data inputs.

C.  QO   =  the level of Q before the indicated input conditions were established. D.  WOB1  =  The first bit of word O, etc.

Device type O2
