MIL-M-38510-209 Microcircuit, Digital, 8192-Bit, Schottky, Bipolar, Programmable Read-Only Memory Prom, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, PROM microcircuits which employ thin film nichrome NiCr resistors, zapped vertical emitter, tungsten W, titanium tungsten TiW, or platinum silicide as the fusible link or programming element. Two product assurance class 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.

20/ For unprogrammed devices (circuit D), apply 12.0 V on pins 8 and 22 (A0 and A9), select an appropriate address to acquire the desired output state.

21/ For unprogrammed device type 03 (circuit E), apply 13.0 V on pin 4 (A4) and pin 8 (A0); and for unprogrammed device type 04 (circuit E), apply 13.0 V on pin 8 (A0).

22/ For unprogrammed device type 02 and 08 (circuit H), apply 5.0 V on pin 18, 0.0V to pins 5, 6, 7 and 8, 3.0V to pins 1, 2, 3, 15, 16 and 17, 9.0V to pin 4.

23/ For unprogrammed device type 04 (circuit H) apply 5.0V to pin 24; 0.0V to pins 3, 5, 6, 7, 8, 20 and 21; 3.0V to pins 1, 2, 18, 19, 22 and 23; 9.0V to pin 4.
