What are the key features of ADG3304BCPZ?
- 4-channel bidirectional voltage translation with no direction-control pin needed, simplifying PCB routing
- Operates from 1.2 V to 5.5 V on both A and B ports, covering 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V logic levels
- Automatic direction sensing with propagation delays below 10 ns for high-speed I2C and SPI interfaces
- Ultra-low power consumption in standby mode enables use in battery-powered IoT and wearable devices
What is ADG3304BCPZ used for?
The ADG3304BCPZ is ideal for connecting microprocessors, FPGAs, and memory devices operating at different logic voltages such as 1.8 V and 3.3 V in smartphones, tablets, and embedded computing platforms. It is also widely used in industrial sensor interfaces, portable medical diagnostics, and communication modules where automatic bidirectional translation between 4 signal lines must occur without external direction-control logic.

Frequently Asked Questions
What supply voltage range does the ADG3304BCPZ support on both its A and B ports?
The ADG3304BCPZ supports independent supply voltages from 1.2 V to 5.5 V on each port, allowing it to translate between any two logic levels in that span, such as 1.2 V LPDDR4 interfaces on one side and 3.3 V microcontroller I/O on the other, without additional components.
How does the ADG3304BCPZ determine signal direction without a dedicated direction-control pin?
The ADG3304BCPZ uses a voltage-threshold sensing mechanism to automatically detect which port is driving the signal and routes it to the other port accordingly, supporting propagation delays under 10 ns. This eliminates the need for a host processor to toggle a direction pin, reducing firmware complexity and I/O pin count in designs with 4 bidirectional channels.
For a portable medical device with a 1.8 V ASIC and a 3.3 V display controller, why choose the ADG3304BCPZ over a passive resistor divider?
A passive resistor divider only translates in one direction and slows signal edges, causing timing violations above a few hundred kilohertz. The ADG3304BCPZ actively drives both sides at the full rail voltage, supports bidirectional data flow at SPI speeds exceeding 10 MHz, and consumes only microamperes in standby, making it far better suited to 1.8 V to 3.3 V translation in a battery-constrained medical device.
What package does the ADG3304BCPZ use, and how many channels does it provide?
The ADG3304BCPZ comes in a 16-lead LFCSP package with a 3 mm x 3 mm footprint, housing 4 independent bidirectional translation channels. The small package footprint and low lead count make it suitable for space-constrained PCBs in wearable devices, smartphones, and compact industrial modules.
