General Description

The A278308A chip is a high-performance 2,097,152 bit

one-time programmable read only memory (OTP EPROM)

organized as 256K by 8 bits. The A278308A requires only

5V power supply in normal read mode operation and any

input signals are TTL levels. The A278308A is available in

industry standard 32 pin dual-in-line and 32 pin PLCC

packages.
