Description
The ST1G3236 is a dual supply low voltage
CMOS 1-bit bus Transceiver fabricated with submicron 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. V
CCA
and V
CCB
can be powered from
1.2V to 3.6V respectively. The DIR pin is designed to track V
CCB
.
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.

ST1G3236 Maximum rating
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.
