Product Summary

The PCA9538D is a 16-pin CMOS device that provide 8 bits ofGeneral Purpose parallel Input/Output (GPIO) expansion with interrupt and reset for I2C/SMBus applications and was developed to enhance the Philips family of I2C I/O expanders. The PCA9538D consists of an 8-bit Configuration register (Input or Output selection) ; 8-bit Input register, 8-bit Output register and an 8-bit Polarity inversion register (Active HIGH or Active LOW operation) .

Parametrics

PCA9538D absolute maximum ratings: (1) Supply voltage VDD: -0.5 to 6.0V; (2) DC input current II: ±20mA; (3) DC voltage on an I/O VI/O: Vss -0.5 to 5.5V; (4) DC output current on an I/O II/O: ±50mA; (5) Supply current IDD: 85mA; (6) Supply current ISS: 100mA; (7) Total power dissipation Ptot: 200mW; (8) Storage temperature range Tstg: -65 to 150° C; (9) Operating ambient temperature: -45 to +85° C; (10) Maximum junction temperature: +125° C.

Features

PCA9538D features: (1) 8-bit I2C GPIO with interrupt and reset; (2) Operating power supply voltage range of 2.3 V to 5.5V; (3) 5 V tolerant I/Os; (4) Polarity inversion register; (5) Active LOW interrupt output; (6) 8 I/O pins which default to 8 inputs; (7) 0 kHz to 400 kHz clock frequency; (8) ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101; (9) Latch-up testing is done to JESDEC Standard JESD78 which exceeds 100 mA; (10) Offered in three different packages: SO16, TSSOP16, and HVQFN16.
