ST1G3234
1-bit dual supply bus buffer level translator
with A-side series resistor
Features
■ High speed: tPD = 4.4ns (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
|IOHA| = IOLA = 6mA Min at
VCCA = 2.3V; VCCB = 1.4V 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 (1.2V data
retent)
VCCB(Opr) = 1.4V to 3.6V (1.2V data
retent)
■ 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
Flip-Chip 5
Description
The ST1G3234 is a dual supply low voltage
CMOS 1-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.
All inputs are equipped with protection circuits
against static discharge, giving them ESD
immunity and transient excess voltage.

Stressing the device above the rating listed in the “Absolute Maximum Ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.

In order to meet environmental requirements, ST offers these devices in ECOPACK®
packages. These packages have a Lead-free second level interconnect . The category of
second level interconnect is marked on the package and on the inner box label, in
compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an ST trademark.
ECOPACK specifications are available at: www.st.com
