WS57C291C

WS57C191C/291C MILITARY HIGH SPEED 2K x 8 CMOS PROM/RPROM KEY FEATURES Ultra-Fast Access Time — t ACC = 35 ns — t CS = 20 ns Pin Compatible with Am27S191/291 and N82S191 Bipolar PROMs Immune to Latch-UP — Up to 200 mA Low Power Consumption Fast Programming Available in 300 and 600 Mil DIP ESD Protection Exceeds 2000V GENERAL DESCRIPTION The WS57C191C/291C is an extremely High Performance 16K UV Erasable Electrically Re-Programmable Read Only Memory (RPROM). It is manufactured in an advanced CMOS technology which enables it to operate at Bipolar PROM speeds while consuming only 25% of the power required by its Bipolar counterparts. The WS57C191C/291C is also configured in the standard Bipolar PROM pinout which provides an easy upgrade path for systems which are currently using Bipolar PROMs. The WS57C191C is packaged in a conventional 600 mil DIP package. The WS57C291C is packaged in a space saving 300 mil DIP package configuration.
