Low-Voltage Octal Bus Transceiver with 3.6 V Tolerant Inputs and Outputs
transceiver which is guaranteed to operate from 1.2-V to 3.6-V.
Designed for use in 1.5V, 1.8V, 2.5V or 3.3 V systems, it achieves
high speed operation while maintaining the CMOS low power
dissipation.
outputs up to 3.6 V.
the DIR inputs. The OE inputs can be used to disable the device
so that the busses are effectively isolated.
discharge.
Features
The TC7MA245FK is a high performance CMOS octal bus
It is also designed with over voltage tolerant inputs and
The direction of data transmission is determined by the level of
All inputs are equipped with protection circuits against static
Low voltage operation: V
High speed operation:t
3.6 V tolerant inputs and outputs.
Output current:I
Latch-up performance: −300 mA
ESD performance: Machine model ≥ ±200 V
Package: VSSOP(US)
Bidirectional interface between 2.5 V and 3.3 V signals. (*1)
Power down protection is provided on all inputs and outputs. (*2)
*1: Do not apply a signal to any bus terminal when it is in the output mode. Damage may result.
*2: All floating (high impedance) bus terminal must have their input level fixed by means of pull up or pull down
resistors.
