micron silicon gate and five-layer metal wiring
or 3.0 V; V
= 1.65 V

C MOS technology. Designed for use as an
PHL
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.
■ Power-down protection on inputs and outputs
■ 26 Ω series resistor on A side
■ Operating voltage range:
– V

CCB
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.
■ Max data rates:
– 380 Mbps (1.8 V to 3.3 V translation)
– 260 Mbps (<1.8 V to 3.3 V translation)
– 260 Mbps (translate to 2.5 V)
– 210 Mbps (translate to 1.5 V)
All inputs are equipped with protection circuits to
protect against static discharge, giving them 2 kV
of ESD immunity and transient excess voltage.
■ Latch-up performance exceeds 500 mA
(JESD17)
■ ESD performance:
– HBM > 2 kV (MIL STD 883 method 3015)
– MM > 200 V

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 high-
impedance state only when OE = high.
2. Unused I/O channel should be connected to GND or to the corresponding supply.
3. The OE and DIRn block is powered by V
and these input logic levels are referenced
CCB
to V
. The OE and DIRn input high level can be equal to or greater than V
, up to
CCB
CCB
V
max.
IHB
4. Any input high level can be higher than the corresponding input supply voltage, up to
V
max (V
max).
IHA
IHB
Example:
= 1.8 V, V
V
= 2.6 V, OE = Low, DIRn = Low (B → A direction)
CCA
CCB
==> if I/O Bn = 3 V, I/O An = 1.8 V
5. If V = V = 0 V and OE = 0 V, An and Bn are isolated even if there is a signal on
CCA
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 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 the other V
.
CC
4. Drive the OE input LOW to enable the device.
1.4
Recommended power-down sequence
1. Drive the OE input HIGH to disable the device.
2. Remove power from either V
.
CC
3. Remove power from the other 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.

1. Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs of the
same device switching in the same direction, either HIGH or LOW (Toslh = | tPLHm – tPLHn |, tOSHL = | tPHLm - tPHLn

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)
