4.11 Programming procedure for circuit E. The waveforms on figure 5E, the programming characteristics in
table IVE and the following procedures shall apply for programming the device:
a. Connect the device in the electrical configuration for programming.
b. Terminate all outputs with a 300 Ω resistor to V
c. Address the PROM with the binary address of the selected word to be programmed. Raise V
d. After a delay of t
e. To verify programming after CE
f. The outputs should be programmed one output at a time since the internal decoding circuitry is capable
g. Repeat 4.11c through 4.11f for all other bits to be programmed.
h. For class S and B devices, if any bit does not verify as programmed, it shall be considered a programming

generating a low level logic output. Programming a fuse will cause the output to go to a high level logic
