P3A9606JK

Dual bidirectional I3C/I²C-bus and SPI voltage-level translator

Rev. 1.0 — 10 May 2021

Product data sheet

1 General description

The P3A9606JK is a 2-bit, dual supply translating transceiver with auto direction

sensing, that enables bidirectional voltage level translation for traditional I²C-bus/SMBus

applications, 12.5 MHz I3C-bus applications and also higher speed SPI applications (with

two devices). It features two 1-bit input-output ports (An and Bn), one output enable input

(OE) and two supply pins (V_CCAand V_CCB). V_CCAcan be supplied at any voltage between

0.72 V and 1.98 V and V_CCBcan be supplied at any voltage between 0.72 V and 1.98 V,

making the device suitable for translating between any of the low voltage nodes (0.8 V,

1.2 V and 1.8 V). V_CCAmust be ≤ V_CCBto ensure proper operation.

P3A9606JK can be used for both open drain as well as push-pull application which

allows for level translation applications using I3C, I²C and SPI protocols.

Pins An are referenced to V_CCAand pins Bn are referenced to V_CCB. The active HIGH

OE pin is referenced to V_CCAand controllable by a signal in either V_CCAor V_CCBdomain.

A LOW level at pin OE causes the outputs to be in a high-impedance OFF-state. This

device is fully specified for partial power-down applications using I_OFF. The I_OFFcircuitry

disables the output, preventing the damaging backflow current through the device when it

is powered down.

2 Features and benefits

• Wide supply voltage range:

– V_CCA: 0.72 V to 1.98 V and V_CCB: 0.72 V to 1.98 V; V_CCA≤ V_CCB
