ST2G3236
with side series resistor
QFN10 (1.8 mm x 1.4 mm)
Description
The ST2G3236 is a dual supply, low-voltage
CMOS 2-bit bus transceiver produced with submicron silicon gate and five-layer metal wiring
2
C
MOS technology. Designed for use as an
interface between a 3.3 V bus and a 2.5 V or
1.8 V bus in mixed 3.3 V/1.8 V, 3.3 V/2.5 V and
2.5 V/1.8 V 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 3 V bus,
and the B-port with the 2.5 V and 1.8 V bus.
All inputs are equipped with protection circuits to
protect against static discharge, giving them 2 kV
of ESD immunity and transient excess voltage.

1.2 Application notes and recommendations
1. Once the device is enabled (OE = low), even if the input is floating, output may be either
on high or low logic level only, not in a high-impedance state. Output is in a highimpedance state only when OE
2. Unused I/O channel should be connected to GND or to the corresponding supply.
3. The OE

V
and DIRn block is powered by V
. The OE and DIRn input high level can be equal to or greater than V
CCB
max.
IHB
4. Any input high level can be higher than the corresponding input supply voltage, up to
V
IHA
max (V

Example:

= 1.8 V, V
CCA
= 2.6 V, OE = Low, DIRn = Low (B → A direction)
CCB
==> if I/O Bn = 3 V, I/O An = 1.8 V
5. If V
CCA
= V
= 0 V and OE = 0 V, An and Bn are isolated even if there is a signal on
CCB
An or Bn.
6. If the ST2G3236QTR is used in a UART application, there is a possibility of floating
input condition if the cable is disconnected, therefore a pull-down resistor is
recommended on the input port.
1.3 Recommended power-up sequence
1. Apply power to either VCC.
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 the other V
4. Drive the OE
input LOW to enable the device.
CC
.
1.4 Recommended power-down sequence
1. Drive the OE input HIGH to disable the device.
2. Remove power from either V
3. Remove power from the other V

1. CPD is defined as the value of the IC's internal equivalent capacitance, which is calculated from the
operating current consumption without load. (Refer to Figure 4: Test circuit). Average current can be
obtained by the following equation. ICC(opr) - CPD x VCC x fIN + ICC/16 (per circuit)
