DESCRIPTION
The ST16C32245 is a dual supply low voltage
CMOS 14-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 and it includes 2-bit I2C level
translation. This IC is intended for two-way
asynchronous communication between data
buses and the direction of data transmission is
determined by nDIR inputs. The enable inputs nG
can be used to disable the device so that the
buses are effectively isolated. The A-port
interfaces with the 3V bus, the B-port with the 2.5V
and 1.8V bus. All inputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage. All floating bus terminals during High Z
State don’t need external pull-up or pull-down
resistor.

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 Test Circuit). Average current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/14 (per circuit)
