Performance Implanted CMOS) technology for
high performance, reliability, and low voltage.
These devices feature maximum RAS access times of 60 ns, 70 ns, and 80 ns. All addresses and data-in lines
are latched on chip to simplify system design. Data out is unlatched to allow greater system flexibility.
The TMS4x100 and TMS4x100P are offered in a 20-/26-lead plastic surface-mount small-outline (TSOP)
package(DGAsuffix)anda300-mil20-/26-leadplasticsurface-mountSOJpackage(DJsuffix). Bothpackages
are characterized for operation from 0°C to 70°C.
