HIGH SPEED 2K x 8 CMOS PROM/RPROM
KEY FEATURES Ultra-Fast Access Time • Pin Compatible with Am27S191/291— t ACC = 25 ns
and N82S191 Bipolar PROMsCS = 12 ns
• Immune to Latch-UP Low Power Consumption — Up to 200 mA
Fast Programming • ESD Protection Exceeds 2000V Available in 300 Mil DIP and PLDCC
GENERAL DESCRIPTIONThe 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.

NOTES:1. CMOS inputs: GND ± 0.3V or VCC± 0.3V. TTL inputs: VIL≤ 0.8V, VIH‡ 2.0V. These are absolute voltages with respect to device ground pin and include all overshoots due to system and/or tester noise.
Do not attempt to test these values without suitable equipment.
*NOTICE:Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device.
This is a stress rating only and functional operation of
the device at these or any other conditions above
those indicated in the operational sections of this
specification is not implied. Exposure to absolute
maximum rating conditions for extended periods of
time may affect device reliability.

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.
NOTES:4. This parameter is only sampled and is not 100% tested.
