UV Erasable Programmable Read-Only Memory

The AS27C256 series is a set of 262,144 bit, ultraviolet-light erasable, electrically programmable read-only Memories These devices are fabricated using power-saving CMOS tech- nology for high speed and simple Interface with MOS and bipo- lar circuits. All inputs (including program data inputs) CAN be driven by Series 54 TTL circuits without the use of external pullup resistors. 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 AS27C256 is pin-compatible with 28-pin 256K ROMs and EPROMs It is offered in a 600mil dual-in-line ceramic package (J suffix) and a 450 x 550 mil ceramic LCC (ECA suffix) rated for operation from -55C to 125 By Austin Semiconductor, Inc.
