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 V and ground is recommended.
CC
Inadequate decoupling may result in access time degradation or other transient performance failures.
