These devices are multilevel pipeline registers implemented using a low power CMOS process. They are pin for pin compatible replacements for industry standard multilevel pipeline registers such as the L29C520 and L29C521. The HSP9520 and HSP5921 are direct replacements for the AM29520 and AM29521 and WS59520 and WS59521.
