27C16
16 384-Bit (2048 x 8) UV Erasable CMOS PROM
Military Qualified
General Description
The 27C16 is a high speed 16K UV erasable and electrically
reprogrammable CMOS EPROM ideally suited for applica-
tions where fast turnaround pattern experimentation and
low power consumption are important requirements
The 27C16 is packaged in a 24-pin dual-in-line package with
transparent lid The transparent lid allows the user to ex-
pose the chip to ultraviolet light to erase the bit pattern A
new pattern can then be written into the device by following
the programming procedure
This EPROM is fabricated with the reliable high volume
time proven P
The 27C16 specified on this data sheet is fully compliant
with MIL-STD-883 Revision C
