GENERAL DESCRIPTION

The SMJ27C040 is a set of 4,194,304-bit, ultraviolet-light

erasable, electrically programmable read-only memories

(EPROMs).

These devices are fabricated using CMOS technology for

high speed and simple interface with MOS and bipolar

circuits. All inputs (including program data inputs) can be

driven by Series 54 TTL circuits. Each output can drive one

Series 54 TTL circuit without external resistors. The data

outputs are 3-state for connecting multiple devices to a

common bus.

The SMJ27C040 is offered in a 32-pin 600-mil

dual-in-line ceramic package (J suffix) rated for operation

from -55°C to 125°C.

Since this EPROM operates from a single 5V supply (in

the read mode), it is ideal for use in microprocessor-based

systems. One other (13V) supply is needed for programming.

All programming signals are TTL level. For programming

outside the system, existing EPROM programmers can be

used.
