General Description
The A276308A chip is a high-performance 524,288 bit
one-time programmable read only memory (OTP
EPROM) organized as 64K by 8 bits. The A276308A
requires only 5V power supply in normal read mode
operation and any input signals are TTL levels. The
A276308A is available in industry standard 28 pin dual-in-
line and 32 lead PLCC packages.
