4.17 Programming procedures for circuit J. The programming characteristics in table IVJ and the following
f. The outputs should be programmed one output at a time, since the internal decoding circuitry is capable
g. Repeat 4.16b through 4.16f for all other bits to be programmed.
h. If any bit does not verify as programmed, it shall be considered a programming reject.
a. Connect the device in the electrical configuration for programming. The waveforms on figure 5J and the
b. Address the PROM with the binary address of the selected word to be programmed. Address inputs
c. Disable the chip by applying input high (V
d. Disable the programming circuitry by applying an Output Voltage Disable of less than V
e. Raise V
f. After a delay equal to or greater than t
g. Other bits in the same word may be programmed while the V
h. Lower V
i. Enable the PROM for verification by applying a logic “0” (V
j. Repeat 4.17a through 4.17i for all other bit to be programmed in the PROM.
k. If any bit does not verify as programmed, it shall be considered a programming reject.
