1.5 V LVCMOS (JESD8-11)

Low-Voltage CMOS for 1.5 V is an extension of the LVCMOS standard (JESD8-5) used for general-

purpose 1.5 V applications. It uses a 1.5 V input buffer and a push-pull output buffer.

Notes:

1. Currents are measured at high temperature (100°C junction temperature) and maximum voltage.

2. Currents are measured at 85°C junction temperature.

3. Software default selection highlighted in gray.
