Programming and Verification
The HD4074344 and HD4074394 can be high-speed programmed without causing voltage stress or
affecting data reliability.
Table 24 shows how programming and verification modes are selected.

Precautions
1. Addresses $0000 to $1FFF should be specified if the PROM is programmed by a PROM programmer.
If address $2000 or higher is accessed, the PROM may not be programmed or verified correctly. Note
that the plastic package type devices cannot be erased and reprogrammed. Set all data in unused
addresses to $FF.
2. Be careful of not using the wrong PROM programmer or socket adapter, which may cause an
overvoltage and damage the LSI. Make sure that the LSI is firmly fixed onto the socket adapter, and
that the socket adapter is firmly fixed to the programmer.
3. The PROM should be programmed with V
PP
= 12.5 V. Other PROMs use 21 V. If 21 V is applied to
the HD4074344 or HD4074394, the LSI may become permanently damaged. 12.5 V is Intel’s 27256
