ST4G3235

4-bit dual supply bus buffer level translator

with a side series resistor

Features

■ High speed: tPD = 4.3ns (Max.) at TA = 85°C

VCCB = 1.65V; VCCA = 3.0V

■ Low power dissipation:

ICCA = ICCB = 5µA(Max.) at TA=85°C

■ Symmetrical output impedance:

|IOHA| = IOLA = 10mA Min at

VCCA = 2.75V; VCCB = 1.4V to 3.6V

|IOHB| = IOLB = 4mA Min at

VCCB = 1.65V; VCCA = 1.4 to 3.6V)

■ Balanced propagation delays:

tPLH ≅ tPHL

■ Power down protection on inputs and outputs

■ 26Ω series resistor on a side outputs

■ Operating voltage range:

VCCA(Opr) = 1.4V to 3.6V

VCCB(Opr) = 1.4V to 3.6V

■ Max data rates:

380Mbps (1.8V to 3.3V translation)

260Mbps (<1.8V to 3.3V translation)

260Mbps (translate to 2.5V)

210Mbps (translate to 1.5V)

■ Latch-up performance exceeds 500mA

(JESD 17)

■ ESD performance:

HBM > 2000V (MIL STD 883 method 3015);

MM > 200V

■ ROHS compliant for Flip-Chip package

Description

The ST4G3235 is a dual supply low voltage

CMOS 4-bit bus buffer level translator fabricated

with sub-micron silicon gate and five-layer metal

wiring C2MOS technology. Designed for use as an

interface between a 3.3V bus and a 2.5V or 1.8V

bus in a mixed 3.3V/1.8V, 3.3V/2.5V, 1.8V/1.4V

and 2.5V/1.8V supply systems, it achieves high

speed operation while maintaining the CMOS low

power dissipation.

This IC is intended for one-way asynchronous

communication between data buses. The input

and output power down protections disable the

device when both power supply are down, so that

the buses are effectively isolated.

The input tolerant buffers allow to translate VCCB

compatible signals and greater signals than VCCB

up/down to VCCA and viceversa.

All inputs are equipped with protection circuits

against static discharge, giving them ESD

immunity and transient excess voltage.
