The ST2G3236 is a dual supply low voltage
CMOS 2-bit Bus Transceiver 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 and
2.5V/1.8V supply systems, it achieves high speed
operation while maintaining the CMOS low power
dissipation.

This IC is intended for two-way asynchronous
communication between data buses and the
direction of data transmission is determined by
DIR inputs. The A-port interfaces with the 3V bus,
the B-port with the 2.5V and 1.8V bus.
■ 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)
All inputs are equipped with protection circuits
against static discharge, giving them 2kV ESD
immunity and transient excess voltage.
■ Latch-up performance exceeds 500mA
(JESD17)
■ ESD performance:
– HBM > 2kV (MIL STD 883 method 3015);
– MM > 200V

Recommended power-up sequence is as follows:
1. Apply power to either V
CC
2. Apply power to the OE input and to the respective data inputs. This may occur at the
same time as Step 1.
3. Apply power to other V
CC
4. Drive the OE input LOW to enable the device.
The recommended power-down sequence is as follows:
1. Drive OE input HIGH to disable the device
2. Remove power from either V

Electrical ratings
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.
