* Ultra-Fast Access Time
-- t ACC = 25 ns -- t CS = 12 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 Mil DIP and PLDCC
* 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 as well as a Plastic Leaded Chip Carrier (PLDCC) and a Ceramic Leadless Chip Carrier (CLLCC). The WS57C291C is packaged in a space saving 300 mil DIP package configuration. Both are available in commercial, industrial, and military operating temperature ranges.

A.C. testing inputs are driven at 3.0 V for a logic "1" and 0.0 V for a logic "0." Timing measurements are made at 1.5 V for input and output transitions in both directions.
NOTE: 6. Provide adequate decoupling capacitance as close as possible to this device to achieve the published A.C. and D.C. parameters. A 0.1 microfarad capacitor in parallel with a 0.01 microfarad capacitor connected between VCC and ground is recommended. Inadequate decoupling may result in access time degradation or other transient performance failures.
