PCAL9722HN/Q900HP - NXP

Description: • SPI bus to parallel port expander • 5 MHz SPI bus • Operating power supply voltage range of 1.1 V to 5.5 V on the SPI bus side • Allows bidirectional voltage-level translation and GPIO expansion between 1.1 V to 5.5 V on SPI and 1.8 V, 2.5 V, 3.3 V, 5.5 V on Port P • Low standby current consumption: 2.0 μA typical at 3.3 V VDD • Schmitt trigger action allows slow input transition and better switching noise immunity at the SPI inputs (SCLK, SDIN, CS) – Vhys = 0.11 V (typical) at 1.1 V – Vhys = 0.1
