Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The PCA9505DGGY provides 40-bit parallel input/output (I/O) port expansion for I²C bus applications in 5 groups of 8 I/O. The outputs are capable of pulling out 10 mA and sinking 15 mA at a 5 V supply voltage, allowing direct driving of up to 40 LEDs at a total package load of 600 mA. any of the 40 I/O ports can be configured as an input or output. The output ports are totem pole and their logic state changes on Acknowledge (group change). The PCA9505 is identical to the PCA9506 except for the 100 kΩ internal pull-up resistors on all I/Os.

Features

I²C bus serial interface compatible with standard mode (100 kHz) and fast mode (400 kHz)

2.3 V to 5.5 V operation with 5.5 V tolerant I/Os

40 configurable I/O pins default to inputs at power-up

100 kΩ internal pull-up resistors are included on all I/Os of the PCA9505

Outputs:

Totem pole (10 mA pull-out, 15 mA sink) with edge-rate controlled output structure

Active-low output enable (1) input pin tri-states all outputs

Change output state on Acknowledge

Open-drain active-low interrupt (1) output pin allows monitoring of logic level changes on pins programmed as inputs

Input:

Programmable interrupt mask control for input pins that do not require an interrupt for a state change

Polarity Reversal Register allows the polarity of I/O pins to be reversed on reads

Active-low reset (1) input pin restores the device to its power-up default state

3 programmable address pins allow up to 8 devices on the same bus

Can be inserted with power

Line interference minimisation (IOFF and power-up tri-state)

Signal transient suppression (50 ns noise filter and robust I²C bus state machine)

Low standby current

-40 Cel to +85 Cel operation

ESD protection: over 2000 V HBM per JESD22-A114, over 200 V MM per JESD22-A115, over 1000 V CDM per JESD22-C101

Lockout testing completed in accordance with JEDEC standard JESD78 over 100 mA

Instrumentation and Test & Measurement

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
