ST1G3236
1-bit dual supply bus transceiver level translator
with A-side series resistor
Features
■ High speed: tPD = 4.0ns (Max.) at TA = 85°C
■ Low power dissipation:
ICCA = ICCB = 5μA(Max.) at TA = 85°C
■ Balanced propagation delays:
tPLH ≅ tPHL
■ Power-down protection on inputs and outputs
■ 26Ω series resistor on A-side outputs
■ Operating voltage range:
– VCCA(Opr) = 1.2V to 3.6V
– VCCB(Opr) = 1.2V to VCCA
■ Latch-up performance exceeds 100mA per
JESD 78, Class II
■ ESD performance exceeds JESD22
– 2000-V Human-body model (A114-A)

Description
The ST1G3236 is a dual supply low voltage
CMOS 1-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 1.2V
bus in mixed supply systems of 3.3V/1.2V,
3.3V/2.5V and 2.5V/1.8V, the ST1G3236 achieves
high speed operation while maintaining low power
dissipation. VCCA and VCCB can be powered from
1.2V to 3.6V respectively. The DIR pin is designed
to track VCCB.
The device is intended for two-way asynchronous
communication between data buses and the
direction of data transmission is determined by
DIR inputs.
All inputs are equipped with protection circuits
against static discharge, giving them 2kV 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.
